What are biotic components of ecosystem?
An ecosystem is defined as the structural and functional unit of where the living organisms interact with each other and their surrounding and was coined by A.G.Tansley, an English botanist, in 1935.
The basic components of an ecosystem are Biotic Components and Abiotic Components, both the components are interrelated with each other by doing energy flow.
Biotic components belongs to all living components like autotrophs, heterotrophs and saprotrophs. Autotrophs or producers like plants.
Second is consumer or heterotrophs which depend on other organisms for their food, can be primary consumers, secondary consumers and tertiary consumers.
Primary consumers are herbivores, Secondary consumers can be either carnivores or omnivores. Tertiary consumers get energy from on secondary consumers.
Quaternary consumers are carnivores and Decomposers include saprophytes feed on dead and decaying matter.
Thus option C is correct.
