What is at the top of the food chain?
At the top of the system are the apex predators: animals who have no predators other than humans.
Is a shark at the top of the food chain?
Sharks are an apex predator, which means they are at the top of the food chain. This also means that there are not a lot of them because if there were it would upset the balance of the ocean and they would eat too much until there was no food left in the ocean.
What's a food chain in the ocean?
An ocean food chain shows how energy is passed from one living thing to another in the ocean. Producers make their own food (plankton, algae, seaweed), and consumers eat the producers and/or other consumers to get the energy they need (crabs, shrimp, dolphins, sharks and fish).
Is the killer whale at the top of the food chain?
Killer whales (also called orcas) are apex predators, meaning they are at the top of their food chain. They feed on fish and squid like other odontocetes (toothed whales) do, but will also target seals, sea birds and even whale species far bigger than themselves.
What is the king of the ocean?
Killer Whales When you think of top ocean predators, you probably think of sharks. Great white sharks, to be exact. But the true ruler of the sea is the killer whale. Killer whales are apex predators, which means they have no natural predators.
Why are sharks scared of dolphins?
As sharks are mostly solitary hunters and quite slow, they end up being no match in the face of a pod of dolphins. Groups of dolphins are so scary that sharks have been known to stay away from the parts of the ocean where dolphins are known to live, swimming away to safer water!
How many levels of food chains are in the ocean?

What are the main producers in the ocean?
The principal marine primary producers are cyanobacteria, algae and marine plants. The oxygen released as a by-product of photosynthesis is needed by nearly all living things to carry out cellular respiration.
What eats a shark in a food chain?
Yes! The great white shark has been thought of as the untouchable predator of the ocean, but in fact killer whales (or orcas) are actually quite skilled in attacking a great white. Orca's hunt in packs, similar to wolves and have been known to work together in tactical ways to capture and attack their prey.
What kills killer whales?
Orcas are apex predators, which means they're at the very top of the food chain and they have no predators. Killer whales are some of the largest and most powerful animals in the ocean, and no other predator is able to challenge them.

What is the food web in the ocean?
The primary marine food web, which is based on plant productivity, includes many of the sea's species— but not all of them . There are other deep-ocean ecosystems that are entirely independent of the sunlight energy that kick-starts the main marine ecosystem.
What are the organisms that saturate the ocean?
Countless billions of one-celled organisms, called phytoplankton, saturate sunlit upper-ocean waters worldwide. These tiny plants and bacteria capture the sun's energy and, through photosynthesis, convert nutrients and carbon dioxide into organic compounds. On the coast, seaweed, and seagrasses do the same thing.
What are the animals that live in the ocean?
On the ocean's surface waters, microscopic animals—zooplankton, which include jellyfish and the larval stages of some fish, barnacles, and mollusks— drift across the sea, grazing opportunistically. Larger herbivores include surgeonfish, parrotfish, green turtles, and manatees.
What is the adjective for marine ecosystem?
marine. Adjective. having to do with the ocean. marine ecosystem. Noun. community of living and nonliving things in the ocean. photosynthesis. Noun. process by which plants turn water, sunlight, and carbon dioxide into water, oxygen, and simple sugars.
What are the two plants that produce the most oxygen?
They also produce more than half of the oxygen that we breathe on Earth. Level Two: Herbivores.
How many marine species are there?
Some 300,000 marine species are known to science—about 15 percent of all the species identified on the planet. But the sea is so vast that a million or more as yet unknown species may live in its waters. Most of these aquatic species are tied together through the food web.
Which organisms produce their own food?
organism that can produce its own food and nutrients from chemicals in the atmosphere, usually through photosynthesis or chemosynthesis. organism that eats meat. group of organisms linked in order of the food they eat, from producers to consumers, and from prey, predators, scavengers, and decomposers.
Ocean Food Chains
Do you ever wonder what you are going to eat for lunch or dinner at the beginning of the day? Food is very important for us and for all animals and plants to survive. However, most animals in our world don't plan their next meal. Rather, they know that they are dependent on a basic type of food source to provide them.
Food webs
When looking at a food chain, there is usually not one marine animal that eats the one type of kelp. Sometimes, there are multiple species of marine animals that are dependent on kelp, making multiple food chains. These multiple connections of the food chains are known as food webs.
Different Types of Ocean Food Chains
Food chains are different from one oceanic environment to another. This occurs because there are many different environments and climates around the world. Because of this, a specific group of organisms is adapted to live in certain environments.
What are the three parts of the ocean food chain?
located in the ocean. These living organisms are divided into three parts known as plankton, nekton, and benthos. These living organisms survive on each other and thus controls the ocean food chain.
Why is the ocean food chain important?
Ocean food chains are an important source of food. This food chain is much larger than the food chain of all ecosystems, as millions of aquatic species are found here. All these organisms survive by eating each other. So this food chain is a very important source of food.
What is the animal that floats on the surface of the ocean?
The zooplankton is an aquatic animal that floats on the surface of the ocean. They feed on various phytoplankton, unicellular plants, algae, etc. floating on the sea surface (2) & (4). 3. Secondary consumer. Some animals present in an ecosystem that takes primary consumers as food are called secondary consumers.
What is the largest ecosystem in the world?
The ocean ecosystem is the largest of all the ecosystems in the world and is located in the largest surface area of the world. The total volume of all oceans is about 15 times that of land. There are a total of five oceans on this planet. About 70% of the earth’s surface is covered by oceans and these oceans are extremely large and deep. The temperature and salinity of ocean water vary based on depth. The biodiversity of these oceans is very high, as it is home to millions of aquatic plants and animals. These species make up the ocean food chain. The ocean food chain is discussed below (2) & (3).
What is the main producer of the ocean food chain?
The phytoplankton is the main producer of the ocean food chain. These phytoplankton floats on the ocean surface. They usually range in diameter from 0.06 mm to 3 mm. Sometimes the diameter of the phytoplankton is more than 3 mm.
How do phytoplankton make food?
They make food in the process of photosynthesis with the help of sunlight. They convert solar energy into chemical energy while making food with the help of sunlight. This phytoplankton after using the generated food energy for their own work, transfer the remaining energy to the next level (2) & (5). 2.
What are the decomposers of the ocean?
Decomposer. The primary decomposer in the ocean food chain is bacteria. Fungi, ocean worms, echinoderms, mollusks, echinoderms, etc. are the other decomposers of the ocean ecosystem. All these fungi and bacteria cause the decay of the producers and consumers of the ocean ecosystem (1).
How does the ocean food chain work?
An ocean food chain shows how energy is passed from one organism, living thing, to another in the ocean. You can think of a food chain like an actual chain. A chain has different sections or parts called links. In a food chain, the different links represent different organisms.
What are some examples of producers in the ocean?
A producer is a living creature that needs the sun to help it make its own food. Examples of producers in the ocean are algae, seaweed and plankton.
What is it called when a dolphin eats fish?
As the fish swims off, a dolphin eats the fish. The dolphin is the third to eat in this scenario, so it is called a tertiary consumer. So, as you eat your seafood dinner, know that your family has now become part of this food chain. Let's review!
What is the first thing a shrimp eats?
A small shrimp swims up to the algae and starts to eat the plankton. Since the shrimp is the first to eat, it is called a primary consumer. As the shrimp eats the plankton, some of the energy stored in the plankton is lost. Just as the shrimp starts to swim off, it is eaten by a fish.
What is the second consumer of fish?
Since the fish is the second consumer, it is called a secondary consumer. As the fish eats the shrimp, it receives only some of the energy stored in the shrimp. If the fish had eaten the plankton, he would have received more energy than he would from the shrimp. As the fish swims off, a dolphin eats the fish.
What are the three types of consumers?
There are three different types of consumers: primary consumers, secondary consumers and tertiary consumers.
What is the link in the chain?
Link in the Chain. You sit down to eat a meal with your family, when you look down at your plate and notice that you will be eating seafood.
