The carbon cycle is a natural process that describes the movement of carbon among the Earth’s atmosphere, oceans, soil, and living organisms. It operates through several key processes:

1. Photosynthesis: Plants absorb carbon dioxide (CO₂) from the atmosphere and convert it into organic matter (glucose) using sunlight, releasing oxygen in the process.
2. Respiration: Animals and plants release CO₂ back into the atmosphere through respiration, as they break down organic matter for energy.
3. Decomposition: When organisms die, decomposers (like bacteria and fungi) break down their bodies, releasing carbon back into the soil and atmosphere.
4. Combustion: The burning of fossil fuels (coal, oil, and natural gas) releases stored carbon as CO₂ into the atmosphere, contributing to the greenhouse effect.

Impact of Deforestation on the Carbon Cycle:

Deforestation significantly disrupts the carbon cycle in several ways:

1. Reduced Carbon Sequestration: Trees act as carbon sinks, absorbing CO₂ during photosynthesis. When forests are cut down, this capacity is diminished, resulting in higher atmospheric CO₂ levels.
2. Carbon Release: The destruction of trees and vegetation releases stored carbon back into the atmosphere, exacerbating greenhouse gas concentrations.
3. Loss of Biodiversity: Deforestation leads to habitat destruction, reducing biodiversity. Healthy ecosystems are essential for maintaining the balance of the carbon cycle.
4. Soil Erosion: Without tree roots to anchor the soil, erosion increases, leading to the loss of carbon-rich soil and further carbon release.

Overall, deforestation accelerates climate change by increasing atmospheric CO₂ levels, thereby disrupting the natural balance of the carbon cycle.
