What is the carbon cycle?

Back

The carbon cycle is the process by which carbon is exchanged between the atmosphere, land, water, and living organisms. It involves processes like photosynthesis, respiration, decomposition, and combustion.

What role does photosynthesis play in the carbon cycle?

Back

Photosynthesis allows plants to absorb carbon dioxide from the atmosphere and convert it into glucose (food) using sunlight.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which living organisms take in oxygen and release carbon dioxide to produce energy.

Front

How do animals contribute to the carbon cycle?

Back

Animals contribute to the carbon cycle by breathing in oxygen and exhaling carbon dioxide during cellular respiration.

Front

What happens to carbon in dead organisms?

Back

Dead organisms can decompose and release carbon back into the soil and atmosphere, or they can be buried and eventually form fossil fuels.

Front

What are fossil fuels?

Back

Fossil fuels are natural substances formed from the remains of ancient plants and animals, which can be burned for energy, releasing carbon dioxide into the atmosphere.

Front

What is the greatest contributor to atmospheric carbon?

Back

Transportation is the greatest contributor to atmospheric carbon due to the burning of fossil fuels in vehicles.

Front

What is the impact of burning fossil fuels on the carbon cycle?

Back

Burning fossil fuels releases large amounts of carbon dioxide into the atmosphere, contributing to climate change.

Front

What is the role of decomposers in the carbon cycle?

Back

Decomposers break down dead organic matter, returning carbon to the soil and atmosphere, and making nutrients available for plants.

Front

How does carbon dioxide enter the atmosphere?

Back

Carbon dioxide enters the atmosphere through processes like respiration, combustion of fossil fuels, and decomposition.
