How carbon moves in the carbon cycle.
6.	Energy flows in one direction in ecosystems (sunà producers à consumers), but elements move in cycles among reservoirs, such as, the solid earth, oceans, atmosphere, and organisms. These cycles are called biogeochemical cycles. The carbon cycle is an example of a biogeochemical cycle. Describe 2 ways that carbon moves in the carbon cycle. You must indicate the path, mechanism, and whether the process is biotic or abiotic. For example, as part of the carbon cycle, carbon moves from the atmosphere to plants. The mechanism is photosynthesis, and it is a biotic process.
