Ovolcanic eruptions

Answer 1

Forest fires, decomposition of organic matter, and volcanic eruptions release CO₂ into the atmosphere.

Step-by-step explanation:

Forest fires release CO₂ into the atmosphere. During a forest fire, the intense heat causes organic matter in trees and vegetation to break down, resulting in the release of carbon dioxide. Decomposition of organic matter also releases CO₂. When dead plants and animals decompose, they release carbon dioxide as a byproduct. Volcanic eruptions release CO₂ into the atmosphere. When volcanoes erupt, they release gases including carbon dioxide. However, photosynthesis does not release CO₂ into the atmosphere. In fact, photosynthesis is the process through which plants consume CO₂ and produce oxygen. Lastly, reforestation actually helps reduce CO₂ levels in the atmosphere as it involves the planting of trees which absorb CO₂.
