Answer:
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.
