Answer 2

Hii friend good morning ❤️❤️

Here is your answer ✌️✌️✌️

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.
