Why do plants produce oxygen and animal produce carbon dioxide?

Question

Why do plants produce oxygen and animals produce carbon dioxide?

Answer 1

Through photosynthesis, plants can transform sunlight, carbon dioxide, and water into energy for their own use. As a byproduct, they produce oxygen. In contrast, animals require oxygen to obtain energy from the food they eat, and they produce carbon dioxide as a result. Despite their distinct roles in the oxygen and carbon dioxide exchange, plants and animals depend on each other's outputs to thrive within the ecosystem.

Answer 2

Plants produce oxygen and animals produce carbon dioxide as a result of the process of respiration. Plants use the process of photosynthesis to convert carbon dioxide and water into oxygen and organic compounds. Animals, on the other hand, use the process of respiration to convert oxygen and organic compounds into carbon dioxide and water.

Answer 3

Plants produce oxygen and animals produce carbon dioxide as a byproduct, they produce oxygen. In contrast, animals require oxygen to obtain energy from the food they eat, and they produce carbon dioxide as a result. Despite their distinct roles in the oxygen and carbon dioxide exchange, plants and animals depend on each other's outputs to thrive within the ecosystem.
