componets of an ecosystem

An ecosystem consists of two components/environments;
a) The biotic environment. (living component)
Consist of the animal and plant communities. Therefore biotic is considered to be the living organisms, whether micro or macro in size. These form a vital environment of an organism and are in a constant interaction with each other. The plant community is known as flora and the animal community is known as fauna.
b) The abiotic environment.
These are the non living components of an eco system.
They include;
i. Climatic elements of the atmosphere such as rainfall, light, temperature, humidity, air currents (wind), atmospheric pressure, cloud cover etc.
ii. Water bodies of all sizes and characteristics.
Some are fresh water bodies; others are marine (high salt concentration).
iii. Edaphic (soil) factors; include soil structure, profile, texture, pH, temperature etc.
iv. Lithosphere (rock types) factors or land forms e.g. metamorphic rocks, sedimentary rocks and igneous rocks.
