The cow eats the grass; as the grass regrows, it takes carbon dioxide from the atmosphere into its growing leaves and roots (along with other nutrients) and stores the carbon molecules in the soil. The cow that ate the grass also has to excrete her wastes, which turns back into the soil through the act of decomposition. She also releases carbon into the atmosphere, but it is quickly put back into the earth by the plants that breathe it in and exhale oxygen through the act of photosynthesis.
No, this is not true. Human breathing is part of the carbon cycle. We breathe it in, (and we take it in by eating and drinking) and we breathe it out.
Yes, animal waste is part of the carbon cycle. When animals produce waste, it contains carbon from the food they consumed. This carbon can be released back into the environment as the waste decomposes, completing the carbon cycle.
carbon
There are many ways in which an animal is part of the carbon cycle. Animals breathe out carbon dioxide that plants breathe in.
What
Transpiration is a part of the water cycle, not the carbon cycle. In the carbon cycle, carbon moves between the atmosphere, the oceans, and the earth's vegetation and soil. Transpiration is the process in which water is absorbed by plant roots, moves through the plant, and is released as water vapor into the atmosphere.
carbon dioxide
Yes, it is part of the Earth's carbon cycle.
carbon
Carbon sequestration is part of the carbon cycle, so it could be said that is where it occurs. The carbon cycle refers to the circulation of carbon atoms in the biosphere.
Carbon found within limestone rocks.
While photosynthesis requires carbon dioxide and releases oxygen, cellular respiration requires oxygen and releases carbon dioxide. It is the released oxygen that is used by us and most other organisms for cellular respiration.
