Question

Quizplus · Accepted Answer

Energy enters ecosystems as sunlight and flows through the food chain, being transferred from one organism to another. Eventually, most of the energy is converted into heat and lost from the ecosystem. Matter, on the other hand, is constantly cycled within and through ecosystems, being taken up by organisms, incorporated into their tissues, and then released back into the environment through processes such as respiration, excretion, and decomposition. This cycling of matter is essential for the maintenance and growth of living organisms in ecosystems.
