Matter Cycle Model

All living organisms undergo either cellular respiration or photosynthesis, or both. Carbon is either a reactant or product in both processes. With ecosystems consisting of many organisms of all types, carbon moves around in many ways. That is evident in my model, with carbon moving around as different organisms or objects go through different processes.

KEY:

[...] - processes

(--> <--) - movement of carbon

Black labels - carbon sinks
