I need help please I don’t understand this
aleksley [76]

Answer:

2. It is converted into heat and energy.

Explanation:

So every time an animal eats grass, or another animal it receives 10% of the energy that the previous animal/plant had. If a rabbit ate a carrot, 10 percent of the energy the carrot had in it, will go into the rabbit. the question is asking where the 90% energy from the eaten carrot went.

Answer Explanation:

Most of the energy that isn't stored in the animal/plant is lost as heat or is used up by the body as it digests the animal/plant that was eaten. This is because the animals who consume any of the plants/animals receiving the 10% energy take energy to eat the plant/animal. this takes up the other 90%

I hope this helps :))
