Two important natural processes that release carbon into our atmosphere are photosynthesis and respiration.
Well, the carbon cycle provides an example of matter cycling and energy flow in ecosystems. Photosynthesis, digestion of plant matter, respiration, and decomposition are important components of the carbon cycle, in which carbon is exchanged between the biosphere, atmosphere, oceans, and geosphere through chemical, physical, geological, and biological processes.
I have always heard them referred to as "pathogenic" but I believe the answer is pathologic
