What cycle explains the circulation of gases released as waste products by living things?
Understand the Problem
The question is asking to identify which natural cycle is responsible for the circulation of gases, specifically waste products, produced by living organisms. The options given suggest focus on different biogeochemical cycles.
Answer
The carbon cycle.
The cycle that explains the circulation of gases released as waste products by living things is the carbon cycle.
Answer for screen readers
The cycle that explains the circulation of gases released as waste products by living things is the carbon cycle.
More Information
The carbon cycle involves the exchange of carbon among living organisms, including plants, animals, and microorganisms, as well as the atmosphere, oceans, and geosphere. Through processes like respiration and decay, living organisms release carbon dioxide, which plants use for photosynthesis.
Tips
A common mistake is confusing the carbon cycle with the nitrogen cycle. While both are essential biogeochemical cycles, they involve different elements and processes.
