What is the carbon cycle?

Back

The carbon cycle is the process by which carbon is exchanged between the atmosphere, land, water, and living organisms, involving processes such as photosynthesis, respiration, decomposition, and combustion.

What role do animals play in the carbon cycle?

Back

Animals consume plants and other animals, releasing carbon dioxide back into the atmosphere through respiration.

What is decomposition in the context of the carbon cycle?

Back

Decomposition is the process by which dead organic matter is broken down by decomposers, returning carbon to the soil and atmosphere.

What is the greenhouse effect?

Back

The greenhouse effect is the warming of the Earth's surface due to the trapping of heat by greenhouse gases, including carbon dioxide, in the atmosphere.
