Answer 1

Explanation: It is a movement of energy. Why?

This is, the producers like plants, are eaten by primary consumers like insects, and these animals are eaten by carnivorous consumers which are, then, secondary consumers

It is, in short, a current of energy that begins with photosynthesis (plants) and then this energy transfers from one organism to another through nutrition (in animals) . The food chain, therefore, begins with photosynthetic vegetables, which have the ability to create living matter from the inert.
