What is the role of carbon in ecosystems?

Carbon is an essential part of biological molecules, such as carbohydrates, proteins, and fats, and needs to be recycled for ecosystems to function.

How do living organisms uptake carbon?

Carbon is taken out of the atmosphere in the form of carbon dioxide by plants during photosynthesis.

What happens to carbon during photosynthesis?

The carbon is used to make glucose, which can be turned into carbohydrates, fats, and proteins within the biomass of plants.

How is carbon transferred between living organisms?

Carbon is passed on to animals when they feed on plants.

What process releases carbon back into the atmosphere?

Carbon is returned to the atmosphere in the form of carbon dioxide during respiration.

Where does respiration occur?

Respiration occurs in both plants and animals.

What role do microorganisms have in the carbon cycle?

Microorganisms, such as bacteria and fungi, use dead and waste material to fuel respiration, releasing CO2 during decomposition.

What happens to carbon if animals and plants die without decomposers?

The carbon in their bodies can be converted into fossil fuels, which can be burned to release carbon dioxide into the atmosphere.

What is combustion in the context of the carbon cycle?

The burning of fossil fuels, which releases carbon dioxide into the atmosphere.

What is the significance of the carbon cycle?

Carbon is cycled between the atmosphere, the tissues of organisms, and fossil fuels, ensuring its availability for various life processes.
