I think the poster wants only a simple answer, so I am going to answer in simple terms. The fates can be -

1 Used in cellular respiration as fuel and some amount can be converted to useful energy which can be used to build other substances and some energy can be lost as heat.

2.The animal can become prey for other animal.

3.The animal throws away some matter as feces.

I understand the matter portion but, the energy can be lost as heat? I get that it can be used to create substances in the body. And that is only 2 fates of the energy. – John Sep 15 '13 at 15:16
@John it can be passed on from the animal to the prey. – biogirl Sep 18 '13 at 11:38
