Questions and Answers

Explain how decomposition contributes to the carbon cycle and its importance.

Decomposition releases carbon back into the environment when dead organisms are broken down by bacteria and fungi, which is essential for recycling nutrients and maintaining ecosystem balance.

What is the impact of fossil fuel combustion on climate change?

Combustion of fossil fuels releases carbon dioxide into the atmosphere, increasing greenhouse gas concentrations and contributing to global warming.

Describe the role of carbon sinks in mitigating climate change effects.

Carbon sinks, such as forests and wetlands, absorb more carbon dioxide than they release, effectively reducing the overall concentration of greenhouse gases in the atmosphere.

How does desertification affect the carbon cycle?

Desertification decreases the land's capacity to store carbon, as fertile soil is lost, leading to more carbon being released into the atmosphere. Signup and view all the answers
