Question

A food chain is a model that represents how energy and matter are transferred through an ecosystem.

Typically, a food chain has five or fewer links because

A. no organism exists that eats more than five types of food.

B. there are only three categories of organism—producers, consumers, and decomposes.

C. the amount of energy available decreases with the addition of each link.

D. humans are the top predators and are always the fifth link.

Answer 1

Answer: Option C

Step-by-step explanation:

The food chain is a model which is used to show the inter linking of the animals with each other and interdependence of animals and their food on each other.

There are only fewer animals in a food chain because the energy decreases as we up in the the food chain. If there is any other link added to the food chain the energy will decrease more. Only 10 percent of the total energy is transferred from one level to another.

So, because of this reason only fewer levels are found in the food chain.
