Answer 2

A food chain explains which organism eats another organism in the environment. The food chain is a linear sequence of organisms where nutrients and energy is transferred from one organism to the other. This occurs when one organism consumes another organism. It begins with producer organism, follows the chain and ends with decomposer organism. After understanding the food chain, we realize how one organism is dependent upon another species for survival. All food chains may not process if there is absence of bacteria on the earth.
