Food Chain and Food Web
A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another. Whereas a food web consists of all the food chains in a single ecosystem. A food chain usually starts with a producer and ends with a top carnivore.
The energy flow from one level to another level in a food chain gives the trophic level of an ecosystem. The producers come at first trophic level followed by herbivores (primary consumers), then small carnivores (secondary consumers) and large carnivores (tertiary consumers) occupy the fourth trophic level.
Components of Ecosystem – Biotic and Abiotic
The ecosystem is derived from the Greek word ‘Oikos’ which means home and ‘systema’ means system i.e a limited space in which living beings interact with each other and environmental factors. Every ecosystem consists of two components, namely, biotic components and abiotic components.
Biotic components refer to all living organisms in an ecology while abiotic components of an ecosystem are the non-living things. The components of an ecosystem are seen to function as a unit. In this article, we will cover the Ecosystem and its components notes.
