Question

2/23
what does not produce carbon dioxide?
photosynthesis
animal respiration
plants decaying
burning fossil fuels

Explanation:

To determine what does not produce carbon dioxide, we analyze each option:

• Animal respiration: Animals take in oxygen and release carbon dioxide as a waste product of cellular respiration.
• Plants decaying: Decomposition of plants involves microbial activity that breaks down organic matter, releasing carbon dioxide.
• Burning fossil fuels: Combustion of fossil fuels (like coal, oil, gas) produces carbon dioxide as a byproduct.
• Photosynthesis: In photosynthesis, plants use carbon dioxide, water, and sunlight to produce glucose and oxygen. So, photosynthesis consumes carbon dioxide, not produce it.

Answer:

A. Photosynthesis
