How does matter cycle AND energy flow through living and nonliving things in an ecosystem?

Matter cycles through an ecosystem through processes called biogeochemical cycles.

Explanation:

Photosynthesis

Plants build carbohydrates by taking in carbon dioxide from the atmosphere.

Carbon moves through the food chain

As organisms eat other organisms, carbon moves up the food chain. Molecules in the food that contain carbon transform into the organic molecules that make up the living body.

Carbon moves back to the environment

Organisms use food molecules, containing carbon, as a form of energy. The process of cellular respiration breaks down food molecules into carbon dioxide.

Contribution of industry

Humans contribute to moving carbon dioxide back into the atmosphere through the combustion of fossil fuels.

Use of fossil fuels

Today's fossil fuels were formed hundreds of millions of years ago by plants deposited in the Earth. The decomposition of the plants slowed down in such a way that their organic molecules are used for natural gas, coal and oil.

Diffusion into the air

From the oceans, carbon dioxide diffuses into the air. This creates a large amount of carbon, which is then taken in by plants to start the cycle over again.
