As part of the carbon cycle, plants release carbon into the atmosphere through which process?
sedimentation |
|
decomposition |
|
evaporation |
|
photosynthesis |
The carbon cycle represents the ciruit of carbon through Earth's ecosystem. Carbon dioxide (CO2) in the atmosphere is absorbed by plants through photosynthesis. Plants then die and release carbon back into the atmosphere during decomposition or are eaten by animals who breathe (respiration) the carbon into the atmosphere they exhale and produce waste which also releases carbon as it decays.
