Question

1. which process moves carbon from the atmosphere to the biosphere?

volcanic eruptions
cellular respiration
photosynthesis
sexual reproduction

Explanation:

Photosynthesis is the process by which plants, algae, and some bacteria take in carbon - dioxide from the atmosphere and convert it into organic compounds like glucose, thus moving carbon from the atmosphere to the biosphere. Volcanic eruptions release carbon from the Earth's interior to the atmosphere. Cellular respiration releases carbon dioxide from organisms back into the atmosphere. Sexual reproduction is not related to carbon movement between atmosphere and biosphere.

Answer:

C. photosynthesis
