The kinetics of enzymes are affected by temperature, and in turn, the basal metabolism, activity, and other physiological functions of the organism are affected.
Types of Ecosystem Based on Abiotic Factors
Desert Abiotic Factors: Deserts develop ecosystems that are very distinguishable from other environments due to low rainfall. It covers 20% of the earth’s surface that includes Antarctica. Extreme temperature swings are often observed in deserts because open-air and water vapor stabilizes the temperature.
Human Activity Affecting the Ecosystem
At the beginning of the 19 th century, there were two types of moths in the United Kingdom. At that time, the white-bodied peppered moth was common, whose black-speckled white body allowed it to blend in with the tree bark to avoid being eaten by birds.
Abiotic Factors Versus Biotic Factors

How do organisms choose their habitat?
If you could live anywhere in the world, where would it be? Inside a volcano? Underwater? In a cosy house in the city?
Temperature
There is an incredible range of temperatures on our planet, from very hot (around the equator), to very cold (at the poles, high altitudes or deep underwater), and including everything in between. Metabolism is the machinery that keeps organisms alive - and since this machinery is very temperature-sensitive
Water
You've probably heard about or seen news articles about the hunt for water on other planets. This is because life is tied directly to the presence and quality of water. In arid regions, organisms adapt to survive with limited water resources.
Light
As you might have guessed, light is very important for the survival of most plants. Similar to organisms in the desert, plants that receive low illumination learn to photosynthesize optimally in such conditions. In some regions like deep underwater, where all of visible light does not penetrate, marine plants utilize only some wavelengths of light.
Soil
Several characteristics of soil influence life, including composition, grain size, nutrient content, pH, mineral composition, and water holding capacity.
What is the meaning of abiotic factors?

How does elevation affect precipitation?
This factor is mainly the elevation or gradient and it affects temperature and precipitation in an ecosystem or biome. As altitude increases, temperature and density of oxygen decreases. Higher altitudes usually receive snow instead of rain because of low temperature.
What determines the texture of soil?
1. Texture of soil – The texture of soil is determined by the size of the soil particles. The types of soil include sand, silt and clay on the basis of their size differences.
Why is adaptation important for survival?
Adaptation to temperature is essential for the survival of the species/organisms. Organisms which can survive a wide range of temperature are referred to as Eurytherms (cat, dog, tiger, human). Eurythermy can be an evolutionary advantage: adaptations to cold temperatures (cold-eurythemy) are seen as essential for the survival of species during ice ages. In addition, the ability to survive in a wide range of temperatures increases a species' ability to inhabit other areas, an advantage for natural selection. Eurythermy is an aspect of thermoregulation in organisms.

Common examples of abiotic factors are things like: temperature, elevation, wind, and rain. When these abiotic factors are combined, they constitute much of the variation that different ecosystems possess. Levels of abiotic factors such as water, oxygen, and sunlight influence what kinds of organisms are able to live within an ecosystem.
How do abiotic factors affect other abiotic factors?
Abiotic factors influence other abiotic factors, and an excellent example of this is how the wind impacts the humidity and temperature of an area. The direction and speed that wind moves in impacts temperature, as high winds make an area cooler.
Why are savanna and prairie ecosystems different?
As an example, savanna and prairie ecosystems have distinct abiotic factors, having evolved different types of plant life and animal life because of differences in precipitation. Savanna and prairie ecosystems see substantially less precipitation than the jungle or forest ecosystems. However, while precipitation may be the biggest difference between the two ecosystems, other factors like soil composition and amount of land impact the ability for trees to grow in an area, creating environments where trees cannot survive but prairie plants may thrive (and vice versa).
How does temperature affect the environment?
The temperature of both the ambient air and bodies of water in a region impacts how plants, animals, and humans can survive in an ecosystem. Increases and decreases in temperature impact how organisms develop, impacting the metabolic rate of the organism in question.
