How does carbon enter the biotic part of the ecosystem

Photosynthesis

Explanation:

Photosynthesis can be defined as the process in which the plant and other organism convert light energy into chemical energy which can further be used to make organic compounds. Similarly, it is a process that removes carbon dioxide from the atmosphere and then uses it to make organic compounds.

Photosynthesis

Explanation:

When plants die, their carbon compounds are converted into carbon dioxide by the action of saprophytic bacteria and fungi. The carbon dioxide is released back to the atmosphere. If dead bodies of plants are buried in highly acidic or anaerobic conditions, they cannot be acted upon by saprophytes. Instead they are partially decomposed by anaerobic bacteria and accumulate forming peat. Heat and pressure build up in the peat converting it to coal and natural gas that can be combusted to release carbon.
