Do Zooplankton make their own food?
Since they make or produce their own food they are called producers. Organisms which do not create their own food must eat either plants or animals. They are called consumers. Since the water is the home for these special tiny plants; it is also the home for tiny microscopic animals called zooplankton. What type of consumer is a zooplankton?
What eats plankton other than a whale?
- Fish
- Squid (sperm whales hunt giant squid)
- Octopus

Crustaceans are omnivores, although some species eat algae and others like crabs and lobsters are predators and scavengers of other animals, feeding on those that are already dead. Some, like barnacles, remain in place and filter plankton from the water.Dec 13, 2019
What is a zooplankton?
Zooplankton (pictured below) are a type of heterotrophic plankton that range from microscopic organisms to large species, such as jellyfish. Zooplankton are found within large bodies of water, including oceans and freshwater systems. Zooplankton are drifting ecologically important organisms that are an integral component of the food chain.
What are the different types of zooplankton?
Types of Zooplankton. The most important types of zooplankton include the radiolarians, foraminiferans, and dinoflagellates, cnidarians, crustaceans, chordates, and molluscs.
What are cnidarians made of?
Cnidarians are marine species that are characterized by specialized cells called “cnidocytes”, which are used to capture their prey. They have bodies consisting of a jelly-like substance called mesoglea, a mouth, and tentacles that contain the cnidocytes (e.g., jellyfish).
What is the shell of a foraminiferan?
Foraminiferans are a type of amoeboid protest that exhibit an external shell and ectoplasm used to obtain food. While the shell is typically comprised of calcium carbonate, the shells of some species contain other minerals. These zooplankton can be found in the sediment or drifting about the upper surface waters.
Which animal is at the lower end of the food chain?
C is correct. Zooplankton are at the lower end of the food chain and primarily feed on phytoplankton and smaller species of zooplankton. Aquatic mammals are typically large predators in aquatic environments and consume zooplankton species.
What are the different types of organisms that make up the marine ecosystem?
Molluscs. Molluscs are a highly diverse group of organisms, which include squid species as well as sea slugs, and sea snails. Molluscs comprise a large component of all marine life.
Where are marine organisms most commonly found?
Marine species are most frequently found in coral reefs and tidal zones, borrowing into the sediment. This type of zooplankton is important as its borrowing ability oxygenates the sediment, thereby facilitating the growth of aerobic bacterial species and other animals.
What is the role of zooplankton in the aquatic food web?
Through their consumption and processing of phytoplankton and other food sources, zooplankton play a role in aquatic food webs, as a resource for consumers on higher trophic levels (including fish), and as a conduit for packaging the organic material in the biological pump.
Where are zooplankton found?
As a result, zooplankton are primarily found in surface waters where food resources (phytoplankton or other zooplankton) are abundant. Just as any species can be limited within a geographical region, so are zooplankton. However, species of zooplankton are not dispersed uniformly or randomly within a region of the ocean.
How does a protozoan release DOM?
For protozoan grazers, DOM is released primarily through excretion and egestion and gelatinous zooplankton can also release DOM through the production of mucus. Leaching of fecal pellets can extend from hours to days after initial egestion and its effects can vary depending on food concentration and quality.
Why are zooplankton important?
Since they are typically small, zooplankton can respond rapidly to increases in phytoplankton abundance , for instance, during the spring bloom. Zooplankton are also a key link in the biomagnification of pollutants such as mercury. Zooplankton can also act as a disease reservoir.
What are the metazoan zooplankton?
Important metazoan zooplankton include cnidarians such as jellyfish and the Portuguese Man o' War; crustaceans such as copepods, ostracods, isopods, amphipods, mysids and krill; chaetognaths (arrow worms); molluscs such as pteropods; and chordates such as salps and juvenile fish.
What are macrozoolankton?
Macroscopic zooplankton include pelagic cnidarians, ctenophores, molluscs, arthropods and tunicates, as well as planktonic arrow worms and bristle worms . Zooplankton is a categorization spanning a range of organism sizes including small protozoans and large metazoans.
What is the name of the organism that drifts in the ocean?
Plankton are organisms drifting in oceans, seas, and bodies of fresh water. The word zooplankton is derived from the Greek zoon ( ζῴον ), meaning "animal", and planktos ( πλαγκτός ), meaning "wanderer" or "drifter". Individual zooplankton are usually microscopic, but some (such as jellyfish) are larger and visible to the naked eye .
What Do Plankton Eat?
Plankton, just like plants on land, produce their own food through a process called photosynthesis. In this process, plankton convert sunlight into energy, and use this converted energy to form a sugar called glucose, which they store as a source of nutrients.
What Nutrients Do Plankton Need?
Apart from the ingredients phytoplankton use for photosynthesis, they also need other nutrients in order to thrive in the ocean. These nutrients include phosphate, calcium, iron, silicon, and nitrate.
What Kind of Fish Eat Plankton?
Forage fish often prefer plankton as the primary part of their diet. Forage fish are fish who usually travel in groups, known as shoals or schools, but do not hunt for prey on their own. These fish include anchovies, smelts, halfbeaks, herrings, sardines, capelin, butterfish, rockfish, and menhaden.
Can Plankton Be Harmful for the Environment?
While plankton are vital for food chains and in sustaining ecosystems, too much of them can contaminate environments too and can cause serious problems at sea.
What are the animals that eat plankton?
Shrimp and krill are plankton feeders. The most famous animal that consumes plankton are whales, specifically, baleen whales. Baleen whales are named after their long baleen bristle-like hairs that hang from their jaws, which filter sea-water to extract krill and plankton from it. Jellyfish, which are considered large zooplankton, ...
How do plankton make food?
Planktons are photosynthetic organisms; they can manufacture their own food by means of photosynthesis just like what plants do! Planktons get their energy from sunlight, just like plants do, using a process called photosynthesis. The answer to what do plankton eat?
What is a plankton?
Planktons are small and microscopic organisms that live in fresh or seawater. Plankton isn’t a species, it’s the name for a large group of organisms that live in the waters of the world; such as krill, jellyfish, and the eggs and larvae of larger animals. Even sea salp colonies that can grow up to ten meters in length are considered plankton.
Why do plankton drift in water?
Plankton is very small, and because they are so tiny, they are too weak to swim, therefore they simply drift in the water. Planktos literally means ‘made to wander’. Plankton also needs to consume nutrients such as nitrogen, phosphorous, iron and silicic acid, to survive and reproduce.
What is the name of the plant that converts sunlight into energy?
Chlorophyll also exists in terrestrial plants. It is used to convert sunlight into energy in a process known as photosynthesis. The majority of plankton float in the upper level of the ocean, known as the photic zone, where the nutrients they need can be found.
What is a forage fish?
Forage fish are usually small, bait, or oily fish that travel in groups known as schools and shoals. Herrings; known as sardines and pilchards, anchovies, menhaden, capelin, smelts, sand lance, halfbeaks, pollock, butterfish, and juvenile rockfish, are all forage fish that eat plankton.
What Eats Zooplankton? 7 Top Predators
Menhadens are found in large schools that can extend up to 40 miles. They are a sub-species of the herring family and are significantly small.
Are Zooplanktom on the Bottom of the Food Chain?
The marine food chain is a complex system. At the bottom of the food chain are small microscopic plants that our naked eyes cannot see, referred to as phytoplankton. The next small organism is the zooplankton, with some being microscopic and others being visible by our naked eyes.
Conclusion
Zooplankton are important in the marine food chain as they serve as an intermediary species. The disappearance of zooplankton in the marine ecosystem can be catastrophic to marine life and humans. This is due to an increased level of carbon in the air.
Zooplankton Definition
Types of Zooplankton
- The most important types of zooplankton include the radiolarians, foraminiferans, and dinoflagellates, cnidarians, crustaceans, chordates, and molluscs.
What Do Zooplankton Eat?
- Zooplankton consume a variety of bacterioplankton, phytoplankton, and even other zooplankton species. Since such organisms reside at the surface of bodies of water, zooplankton are also typically found in the upper waters.
Zooplankton Examples
- Krill
Krill (shown below) are a type of crustacean found populating oceans throughout the world. Krill consume phytoplankton and other zooplankton species. Krill are consumed by larger marine animals, thus making them a significant contributor to the lower food chain in marine environme… - Jellyfish
Jellyfish (shown below) are a type of cnidarian as described above, and are found residing throughout marine environments; some reside near the surface, while some species can be found in deeper waters. Jellyfish are most commonly found near coastal regions throughout the world.

Summary
Zooplankton are heterotrophic (sometimes detritivorous) plankton (cf. phytoplankton). Plankton are organisms drifting in oceans, seas, and bodies of fresh water. The word zooplankton is derived from the Greek zoon (ζῴον), meaning "animal", and planktos (πλαγκτός), meaning "wanderer" or "drifter". Individual zooplankton are usually microscopic, but some (such as jellyfish) ar…
Overview
Zooplankton are the animal component of the planktonic community ("zoo" comes from the Greek word. for animal). They are heterotrophic (other-feeding), meaning they cannot produce their own food and must consume instead other plants or animals as food. In particular, this means they eat phytoplankton.
Zooplankton are generally larger than phytoplankton, mostly still microscopic but some can be s…
Size classification
Body size has been defined as a "master trait" for plankton as it is a morphological characteristic shared by organisms across taxonomy that characterises the functions performed by organisms in ecosystems. It has a paramount effect on growth, reproduction, feeding strategies and mortality. One of the oldest manifestations of the biogeography of traits was proposed over 170 years ago, namely Bergmann’s rule, in which field observations showed that larger species tend t…
Taxonomic groups
Protozoans are protists that feed on organic matter such as other microorganisms or organic tissues and debris. Historically, the protozoa were regarded as "one-celled animals", because they often possess animal-like behaviours, such as motility and predation, and lack a cell wall, as found in plants and many algae. Although the traditional practice of grouping protozoa with an…
Role in food webs
Grazing by single-celled zooplankton accounts for the majority of organic carbon loss from marine primary production. However, zooplankton grazing remains one of the key unknowns in global predictive models of carbon flux, the marine food web structure and ecosystem characteristics, because empirical grazing measurements are sparse, resulting in poor parameterisation of grazing functi…
Role in biogeochemistry
In addition to linking primary producers to higher trophic levels in marine food webs, zooplankton also play an important role as “recyclers” of carbon and other nutrients that significantly impact marine biogeochemical cycles, including the biological pump. This is particularly important in the oligotrophic waters of the open ocean. Through sloppy feeding, excretion, egestion, and leaching of fecal …
