Question

Which of the following best explains why ecosystems need a continual influx of new energy? a. Photosynthesis feeds herbivores, carnivores, and decomposers. b. As energy is recycled, a small amount is lost as heat. c. Energy flows through an ecosystem and cannot be recycled. d. Cellular respiration does not feed back into other processes. Please select the best answer from the choices provided A B C D

Answer 1

The answer would be C) Energy flows through an ecosystem and cannot be recycled.

Answer 2

The correct answer is option C

There is need of continual flow of energy in the ecosystem because there is no recycling of energy in the ecosystem.

The flow of energy in the ecosystem is unidirectional which states that there is no recycling of energy and loss of energy at every tropic level takes place.

The ultimate source of energy in the ecosystem is sun and the producers use this energy to make food and feed the other animals.

During this process the flow of energy is unidirectional.
