Question

Some organisms in an ecosystem obtain energy and nutrients from plants. These organisms store the energy in their bodies. What happens to the energy in the ecosystem when the organisms die? A. Some of the energy is used by decomposers, and some of the energy is released into the environment as heat. B. A portion of the energy is destroyed, which means the ecosystem must take in more energy from the universe. C. Most of the energy is converted into nuclear energy by decomposers, and the rest of the energy is absorbed by plants. D. All of the energy is lost to the environment, which decreases the total amount of energy available in the ecosystem.

Answer 1

Option A, is correct

The producer intakes energy from the sun and 10 % of energy is passed on to tropic level I, and similarly at each tropic level 10% of the energy is passed on and the decomposer are at the last tropic level. Thus they also receive 10% of energy and rest all is released into the energy.
