How does carbon move through biotic and abiotic sources?

Thus, an abiotic factor (carbon dioxide) helps create a biotic factor (the plants made out of carbohydrates). Once cellular respiration starts in the organism, it releases Carbon dioxide back into the atmosphere, and the cycle repeats

Explanation:

Nutrients move through the ecosystem in biogeochemical cycles. ... The chemicals travel not only through the biotic and abiotic components of an ecosystem, but they also travel through an organism. The abiotic factors of an ecosystem include: (1) water (hydrosphere), (2) land (lithosphere), and (3) air (atmosphere).
