Afood 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 decomposers. 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

C. The amount of energy available decrease with the addition of each link

Explanation

A food chain model is a presentation of the energy and matter flow through an ecosystem. Most food chains have no more than four or five links because too much links in a single food chain will result to inadequate food to the animals at the end. When the links surpass four or five, less energy will be available for the animals at the end of the chain.
