How does carbon enter the biotic part of the ecosystem?

Carbon enters the biotic (living) part of the ecosystem through photosynthesis. Plants of the forests take the carbon in carbon dioxide and fix it in organic compound such as sugar, starch, cellulose and other carbohydrates. Respiration in plants returns carbon dioxide to the atmosphere.

Although this may be the opposite of what you think i will say it anyway. you were brought into this world for a reason and you still have soo much ahead of you. not everybody has an opportunity of living a great life, but it doesn’t give you a reason to end everything. somebody in the world loves you, and imagine what you would do to them if you left forever.
