Carbon and water cycle

What is the carbon cycle?

The carbon cycle is the biogeochemical cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth.

What are the major processes involved in the carbon cycle?

Photosynthesis, respiration, decomposition, and combustion.

How do photosynthesis and respiration contribute to the carbon cycle?

Plants use carbon dioxide from the atmosphere to produce sugars, while animals release carbon dioxide back into the atmosphere through respiration.

What is the water cycle?

The water cycle, also known as the hydrologic cycle, is the continuous movement of water on, above, and below the surface of the Earth.
