Name the following.
Biotic constituents of soil.

Hint: The term “biotic” is made by the combination of two terms, “bio” meaning life and “ic” meaning like. Thus, the term means life-like and is said to all or any living entities present in an ecosystem.

Complete answer:
The biotic constituents refer to all the living beings present in an ecosystem. Their presence and their biological outgrowth influence the balance of an ecosystem. Biotic constituents refer to all living organisms from animals and humans, to plants, fungi, and bacteria. The interactions between several biotic constituents are important for the reproduction of every species and to achieve fundamental requirements such as food, etc. So, the biotic constituents of soil are organic materials, water, air, and minerals. These biotic components help increase soil fertility which is useful for plants and agricultural purposes.

Additional information:
Abiotic constituents refer to all the non-living, i.e. chemical and physical factors present within the atmosphere, hydrosphere, and lithosphere. Sunlight, air, precipitation, minerals, and soil are some samples of abiotic factors. These constituents have a significant impact on the survival and reproduction of species in an ecosystem. For example, without a sufficient amount of sunlight, autotrophic organisms would not be capable of living. When these organisms eventually die, it'll create a shortage of food for primary consumers. This result flows up the food chain, influencing every organism. Therefore, it leads to a lack of balance in the ecosystem.

Note:
Biotic constituents have a crucial function by interacting with the environment. Animals, as well as plants, depend upon one another for their survival. In other cases, biotic constituents, such as the introduction of an invasive species may damage the balance of an ecosystem. Biotic constituents of a marine ecosystem basically contain algae, plankton, bacteria, fish, sharks, whales, penguins and jellyfish, and others.
