Question

12.) why does cellular respiration add carbon dioxide to the atmosphere, but photosynthesis does not?

Explanation:

Cellular respiration is a process in which cells break down glucose and oxygen to produce energy, carbon - dioxide, and water. Carbon - dioxide is a by - product and is released into the atmosphere. Photosynthesis, on the other hand, takes in carbon - dioxide from the atmosphere and uses it along with water and sunlight to produce glucose and oxygen.

Answer:

The statement in the question is incorrect. Cellular respiration does add carbon dioxide to the atmosphere as it is a catabolic process that releases carbon - dioxide as a waste product. Photosynthesis removes carbon dioxide from the atmosphere as it is an anabolic process that uses carbon - dioxide to build organic molecules.
