If animals had alternation of generations like plants, .

10 percent is the correct answer.

Explanation:

10 percent of energy is transferred from the sun to the level indicated.

It can be explained by the help of the 10 percent Rule which means that if energy is transferred in an ecosystem from the one trophic level to next just ten percent of energy will be transferred on.

The most amount of energy is dissipated as heat or is utilized in the method of cellular respiration.

Most of the energy at all trophic levels reduces as it flows in an ecosystem.

Thus only 10 percent of the energy at each trophic level is transferred to the level indicated.

A trophic level is the place of an organism in the energy pyramid.
