Step 1
What is the name of the cycle shown in the diagram?
Answer
The cycle shown in the diagram is known as the Carbon cycle. This cycle illustrates the process through which carbon is exchanged between the atmosphere, land, water, and living organisms. Key processes like photosynthesis, respiration, and combustion demonstrate how carbon moves through different forms. During photosynthesis, plants absorb carbon dioxide from the atmosphere, and through respiration, both plants and animals return carbon dioxide back into the air. Combustion further contributes to this cycle by releasing carbon stored in fossil fuels.
