What is recycled in an ecosystem quizlet?

Consequently, ecologists say that matter cycles through ecosystems. Scientists track the recycling of atoms through cycles called biogeochemical cycles.

Why is it important that matter is recycled?

Most of the energy needed to cycle matter through earth’s systems comes from the sun. The cycling of matter. Because there are only finite amounts of nutrients available on the earth, they must be recycled in order to ensure the continued existence of living organisms.

Which of the following is responsible for the recycling of matter through an ecosystem?

Nature has its own recycling system: a group of organisms called decomposers. Decomposers feed on dead things: dead plant materials such as leaf litter and wood, animal carcasses, and feces.
