i. Abiotic Components:
Ecological relationships are manifested in physicochemical environment. Abiotic component of ecosystem includes basic inorganic elements and compounds, such as soil, water, oxygen, calcium carbonates, phosphates and a variety of organic compounds. It also includes such physical factors and ingredients as moisture, wind currents and solar radiation. Radiant energy of sun is the only significant energy source for any ecosystem. The amount of non-living components, such as carbon, phosphorus, nitrogen, etc. that are present at any given time is known as standing state or standing quantity.

ii. Biotic Components:
The biotic components include all living organisms present in the environmental system
From nutrition point of view, the biotic components can be grouped into two basic components: (a) Autotrophic components, and (b) Heterotrophic components
The autotrophic components include all green plants which fix the radiant energy of sun and manufacture food from inorganic substances. The heterotrophic components include non-green plants and all animals which take food from autotrophs. So biotic components of an ecosystem can be described under the following three heads: i. Producers (Autotrophic components), ii. Consumers, and iii. Decomposers or reducers and transformers.
