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 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 1

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

Step-by-step explanation:

The food chain is a model that reflects the inter linking of the animals with one another and interreliant attributes of animals and their food on one another.

The food chain its well known to be made up of few number of organisms. This is due to a decline in the amount of energy from the bottom to the top of the food chain. As we progress upward in the food chain, the addition of other link in the food chain will cause a further decline in the available energy. It's important to note that just 10 percent of the overall energy is transferred from a level to the other in a food chain.

Thus, this account for why there are fewer levels in the food chain.

Answer 2

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.
