Transcript of Steps of the Carbon Cycle

Steps of the Carbon Cycle
Step 2
Step 3
Animals feed on the plants. Thus passing the carbon compounds along the food chain. Most of the carbon these animals consume however is exhaled as carbon dioxide. This is through the process of respiration. The animals and plants then eventually die.
Step 4
The dead organisms (dead animals and plants) are eaten by decomposes in the ground. The carbon that was in their bodies is then returned to the atmosphere as carbon dioxide. In some circumstances the process of decomposition is prevented. The decomposed plants and animals may then be available as fossil fuel in the future for combustion.
Step 1
Carbon enters the atmosphere as carbon dioxide from respiration (breathing) and combustion (burning).
Carbon dioxide is absorbed by producers (life forms that make their own food e.g. plants) to make carbohydrates in photosynthesis . These producers then put off oxygen.
Another Picture
Human Effects
*Humans exhale Carbon Dioxide
*We eat plants
*When humans die the Carbon returns to the Earth
*We use Fossil Fuels in our daily life
Other Effects
*When organisms die they return Carbon to the planet
*Long dead creatures turn into fossil fuels
*The breath of organisms cycles the carbon in the atmosphere
*It moves constantly
*Effects rocks, trees animals and the air
Why We Need It
Animals produce carbon. Producers absorb that and release oxygen which is needed for our survival. Oxygen is used in respiration.
