Verified step by step guidance

Understand the role of forests in the carbon cycle: Forests act as carbon sinks, meaning they absorb carbon dioxide (CO2) from the atmosphere during the process of photosynthesis.

Recognize the impact of deforestation: When forests are destroyed, the trees that absorb CO2 are removed, reducing the overall capacity of the environment to sequester carbon dioxide.

Consider the release of stored carbon: The destruction of forests often involves burning or decomposition of plant material, which releases stored carbon back into the atmosphere as CO2.

Analyze the balance of gases: With fewer trees to absorb CO2 and more CO2 being released from the destruction of biomass, the concentration of carbon dioxide in the atmosphere increases.

Conclude the effect on atmospheric gases: While the concentration of oxygen (O2) and nitrogen (N2) might not be directly affected by deforestation, the significant increase in CO2 concentration is a direct consequence of forest habitat destruction.
