Question

The tropical rainforests are sometimes called the "lungs of the earth" because of the abundance of plant species.

Which two atmospheric gases are balanced by tropical rainforests?

Answer 1

Tropical rainforests maintain a balance of oxygen and carbon dioxide in the atmosphere through photosynthesis, supporting rapid plant growth due to ideal climatic conditions.

Step-by-step explanation:

Tropical rainforests, also called the "lungs of the earth," play a crucial role in balancing two vital atmospheric gases: oxygen (O2) and carbon dioxide (CO2). These forests have high net primary productivity due to ideal annual temperatures and precipitation, supporting rapid plant growth. Plants perform photosynthesis, absorbing CO2 and releasing O2, thus maintaining a critical balance of these gases in the atmosphere. The rich biodiversity and extensive biomass present in tropical rainforests are essential for this process. However, the alarming rates of deforestation for reasons like cattle production, the timber industry, and slash-and-burn farming, particularly in regions such as the Amazon basin, central Africa, and Southeast Asia, threaten this vital function.
