Answer:
Organisms play an important role in the carbon cycle in the following ways: Plants absorb carbon from the environment in photosynthesis and return it in respiration. Animals obtain their carbon by eating plants; they release carbon in respiration.
For example, in the food chain, plants move carbon from the atmosphere into the biosphere through photosynthesis. They use energy from the sun to chemically combine carbon dioxide with hydrogen and oxygen from water to create sugar molecules.Carbon dioxide is added to the atmosphere naturally when organisms respire or decompose (decay), carbonate rocks are weathered, forest fires occur, and volcanoes erupt. Carbon dioxide is also added to the atmosphere through human activities, such as the burning of fossil fuels and forests and the production of cement.
