Question

Although animals do not perform photosynthesis, their food supply depends on the sugars that photosynthesis produces. What is the other significant benefit to animals that photosynthesis provides?

A. generating ATP and NADPH
B. removing water from the environment
C. adding carbon dioxide to the atmosphere
D. adding oxygen to the atmosphere

Answer 1

I think the answer would be D, because animals also need oxygen to survive.

Answer 2

Option (D)

Explanation:

Photosynthesis is a process in which the green plants have the ability to prepare their own food in the presence of sunlight, carbon dioxide (CO₂) and water (H₂O). This process is possible due to the presence of chlorophyll pigments in the leaves of green plants that uses these molecules and converts them into the water, food (glucose) and oxygen (O₂). This food is then consumed by consumers such as animals and human beings.

This oxygen is then released into the atmosphere, which is essential for every life form on earth. So, the animals are benefited from the photosynthesis process by getting both the food and oxygen.

Thus, the correct answer is option (D).
