Carbon cycle

Question 1

Question 3

Why is the recycling of materials essential?

Answer 3

Question 4

What are the steps of the Carbon Cycle?

Answer 4

• 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.
