Step 1
What is the name of the cycle shown in the diagram?
Answer
The cycle depicted in the diagram is the Carbon cycle. This cycle illustrates the processes of photosynthesis, respiration, decay, and combustion, which all involve the movement of carbon in various forms through the ecosystem. The primary components include plants absorbing carbon dioxide to produce oxygen via photosynthesis, animals respiring and releasing carbon back into the atmosphere, and the decay of organic matter contributing to the carbon in the soil and atmosphere.
