Question

Difference between carbon,oxygen and chemical cycle

Answer 1

Carbon Cycle:

1. Carbon enters the atmosphere as carbon dioxide from respiration and combustion.

2. Carbon dioxide is absorbed by producers to make carbohydrates in photosynthesis.

3. Animals feed on the plant and as a result the carbon is passed along the food chain. Most of the carbon they consume is exhaled as carbon dioxide formed during respiration.

4. At some point the organisms die, and they are eaten by decomposers. The carbon in their bodies is returned to the atmosphere as carbon dioxide. When decomposition is blocked in some cases, the plant and animal material can be available as fossil fuels for future combustion.
The carbon cycle takes about 100-200 million years to complete

Oxygen Cycle:

In the biosphere, oxygen experiences respiration and photosynthesis. In respiration, humans and animals take in the oxygen, used in metabolic processes. They then release carbon dioxide. Plants and phytoplanktons use the released carbon dioxide to aid in photosynthesis, where they produce carbohydrates and oxygen. The oxygen is released as a byproduct, ready to be used once again by the humans and animals.

Chemical cycle:

The flow of chemical elements and compounds between living organisms and the physical environment.Chemicals absorbed or ingested by organisms are passed through the food chain and returned to the soil, air, and water by such mechanisms as respiration, excretion, and decomposition. As an element moves through this cycle, it often forms compounds with other elements as a result of metabolic processes in living tissues and of natural reactions in the atmosphere, hydrosphere, or lithosphere.
