Which process moves carbon from the atmosphere into living organisms?

Explanation:
Photosynthesis is the process by which living things pull carbon dioxide from the air and convert it into organic matter using sunlight. Plants, algae, and some bacteria take in CO2 and fix its carbon into sugars like glucose, which become part of their tissues. This moves carbon from the atmosphere into living organisms and starts the flow of carbon through the food web. While respiration releases CO2 back into the atmosphere as organisms break down sugars for energy, and decomposition or combustion return carbon to the air after death or burning, photosynthesis is the step that takes atmospheric carbon into biological material.
