What percent of energy is transferred from the sun to the level indicated? food pyramid showing plants at the bottom level. insects and snails are in the second ascending level. the small fish are in the third ascending level. larger fish are in the fourth ascending level. the top level has a hawk. the blue arrows are pointing to the plants at the bottom level of the pyramid. 50 percent 100 percent 90 percent 10 percent

The correct answer would be 10 percent.

It can be explained with the help of ten percent law which states that only 10 percent of the total energy available at any trophic level is passed on the higher trophic level.

Most of the energy is lost as heat or is used in the process of cellular respiration.

Thus, only 10 percent of the energy of the sun would be transferred to the plants or primary producers.

Option D, 10 percent

Explanation:

After organizing the species mentioned here in order of energy transfer, we get-

Base Level - plants

Level 1 -  Insects and snails

Level 2 - small fish

Level 3 - Larger fish

Level 4 - hawk

At each level , only 10% of energy as compared to its previous level is transferred.

Let us suppose that the plant has 1000 joules of energy . Then the energy transferred at each level would be

Level 1 -   10 percent of 1000  Joules i.e 100 Joules

Level 2 -   10 percent of 100  Joules i.e 10 Joules

Level 3 -    10 percent of 10  Joules i.e 1 Joules

Level 4 -    10 percent of 1  Joules i.e 0.1 Joules

Hence, option D is correct
