Part B -
Carbon cycle reservoirs and processes
The carbon cycle describes the cycling of carbon between Earth's biotic (living) and abiotic (nonliving) reservoirs. Identify the major reservoirs and processes in the
carbon cycle by labeling the diagram below.

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 .
