Carbon enters a consumer contained in the complex molecules of the food the consumer eats.
Carbon exits the consumer as a gas called Carbon Dioxide - which is usually breathed out.
Carbon dioxide (CO2) is the molecule that enters a leaf from the atmosphere during photosynthesis.
The lungs are the organs where oxygen enters the body and carbon dioxide leaves it through the process of respiration. Oxygen is taken in when breathing and carbon dioxide is released when exhaling.
atmosphere
Carbon in the atmosphere is taken up by plants during photosynthesis. Through this process, carbon dioxide is converted into organic compounds that are used by plants to grow. This carbon is then transferred to animals when they consume plant material.
Carbon dioxide enters a leaf through small openings called stomata on the surface of the leaf. The stomata open to allow carbon dioxide to diffuse into the leaf from the surrounding air. Once inside the leaf, carbon dioxide is used during photosynthesis to make glucose and oxygen.
combustion
it has no choice but to
Volcanos.
respiration
Volcanos.
siol
it should still be carbon, but too much carbon is bad for the atmosphere. Google: "Carbon in atmoshpere" and see why it's bad
Carbon enters the web of life primarily through photosynthesis, where autotrophs like plants and algae convert carbon dioxide into organic compounds. These autotrophs are then consumed by heterotrophs, passing carbon along the food chain. Carbon is also cycled through decomposers as they break down organic matter and release carbon back into the environment.
All life is based on carbon - it is the main component of biological compounds. It enters life through the atmosphere, through the oceans, and through plants.
Both carbon dioxide and oxygen found in air enters through the stomata. More at Link
carbon exist in earth crust as 0.02% and in atmosphere 0.03%
