Question

Where did the mass of the forest tress come from? What happen to that mass when the forest burns?

Answer 1

Answer:

The mass of the forest comes from carbon and carbon is retrieved from carbon-dioxide that trees used during the process of photosynthesis. In the process of photosynthesis, carbon-dioxide is utilised from the atmosphere by trees and release oxygen and ATP.

When the forest burns the mass again releases to atmosphere in the form of carbon which causes air pollution and increases carbon content in the atmosphere.
