1
Q

A
In all living organisms
2
Q
Why is carbon recycled?
A

3
Q

A
They provide the building blocks for future generations.
4
Q
What are the steps of the Carbon Cycle?
A
- Carbon is removed from the atmosphere by producers (e.g algae) who use it in photosynthesis.
- By consuming plant matte, animals obtain carbon compounds.
- Carbon is returned into the atmosphere (as carbon dioxide) because of the respiration that happens in plant and animal cells.
- When animals and plants die, decomposers return the carbon locked in their bodies back to the atmosphere via decay.
- Combustion of fossil fuels is another source of carbon entry into the atmosphere.
