A dog eats a pound of dog food. What happens to the energy and chemical nutrients in the food over the next several days?
Black_prince [1.1K]

Answer:

The energy is mostly released as heat through the dog's activities; the nutrients either become part of the dog's body or are released to the ecosystem as wastes like urine, feces, and exhaled gases.

Explanation:

  • The food that is consumed by an organism is digested and the nutrients obtained from the food are partly absorbed by the digestive system and assimilated and stored into the body and the nutrients that are not absorbed are released in the form of feces.
  • The chemical energy obtained from the food is released in the form of heat through the activities that are done by the dog.
