Answer:
D) balance consumption of food with use and storage of nutrients
Explanation:
Animals are heterotrophic organisms and derive their nutrition from plants and/or other animals. Digestion of ingested food breakdown the nutrients into simpler substances. These simpler forms of nutrients are either oxidized to obtain the energy stored in them or are stored to serve as fuel in the future when the need arrives.
The energy released by the oxidation of nutrients is stored in form of ATP which serves as a source of energy as and when required. For example, glucose can either oxidized to form ATP or may be stored in the liver and muscle cells in the form of glycogen. A balance between the use of nutrients and their storage allows the animals to perform the vital activities by using the energy and to have stored a reservoir of nutrients to be used under emergency conditions.
Other animals eat grass and as the food chain goes on the hawk eats the food that ate the the grass after getting eaten during many others transforming energy the more the hawk eats the more energy it has

It isn't like there is an actual scientific controversy about it. They clearly show organisms radiating into to new types of animals and they undeniably prove evolution beyond any rational doubt. DNA evidence is probably even better and it completely supports the basic assumptions though there have been a few surprises since the fossil record isn't entirely complete. </span>
