Which natural process helps reduce the amount of carbon dioxide in the air?

  1. Decomposition of dead animals
  2. Combustion of coal and oil
  3. Photosynthesis ✓
  4. Release of gases from volcanoes
Explanation

In photosynthesis, green plants take in carbon dioxide and use it with water and light to make food. This lowers the CO₂ in the air.

Decomposition, burning coal and oil, and volcanic gases all add CO₂ to the air.
