SSC CHSL 2022 PYQ — Question 35

The correct answer is option 4 i.e. In the food chain, the energy level increases from the lower trophic level to the higher trophic level.

• A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another.
• In a food chain, each organism occupies a different trophic level, defined by how many energy transfers separate it from the basic input of the chain.
• In ecology, a food chain is a series of organisms that eat one another so that energy and nutrients flow from one to the next.
• For example, if you had a hamburger for lunch, you might be part of a food chain that looks like this: grass →→right arrow cow →→right arrow human.
