The carbon cycle is one of many biogeochemical cycles on Earth. Can you identify the main features of a biogeochemical cycle and show how the carbon cycle exhibits these features?
Drag the terms on the left to the appropriate blanks on the right to complete the sentences. Not all terms will be used.
1. In a biogeochemical cycle, a chemical element spends time in different places, called reservoirs.
2. As a chemical element moves through a biogeochemical cycle, it moves between "bio" and "geo." The "bio" in biogeochemical refers to biotic reservoirs, or living organisms.
3. The "geo" in biogeochemical refers to Earth--specifically, to the abiotic reservoirs where a chemical element can be found.
4. In the terrestrial carbon cycle, the abiotic reservoir from which living organisms directly obtain their carbon is the atmosphere.
5. Carbon moves from an abiotic reservoir to living organisms during the process of photosynthesis.
6. Carbon moves from living organisms to an abiotic reservoir during the process of cellular respiration.
