Question

carbon constantly cycles into, out of, and within the biosphere. two key biological processes of the carbon cycle are photosynthesis and cellular respiration, which primarily exchange carbon between the biosphere and the atmosphere. complete the sentences to identify the chemical inputs (reactants) and outputs (products) of photosynthesis and cellular respiration. in photosynthesis, carbon dioxide and water are and glucose and oxygen are. in cellular respiration, carbon dioxide and water are and glucose and oxygen are.

Explanation:

Photosynthesis uses carbon dioxide and water as reactants to produce glucose and oxygen. Cellular respiration uses glucose and oxygen as reactants to produce carbon dioxide and water.

Answer:

In photosynthesis, carbon dioxide and water are reactants and glucose and oxygen are products.
In cellular respiration, carbon dioxide and water are products and glucose and oxygen are reactants.
