B-LS2-5 Carbon Cycle

Front

What is the carbon cycle?

Back

The carbon cycle is the process by which carbon atoms are recycled through the Earth's ecosystems, including the atmosphere, oceans, soil, and living organisms.

Front

What role do plants play in the carbon cycle?

Back

Plants absorb carbon dioxide from the atmosphere during photosynthesis, converting it into organic matter.

Front

What is the effect of combustion of fossil fuels on the carbon cycle?

Back

Combustion of fossil fuels releases carbon dioxide into the atmosphere, increasing greenhouse gas concentrations.

Front

How does carbon move from plants to animals?

Back

Carbon moves from plants to animals through the food chain when animals consume plant matter.

Front

What happens to carbon in decomposing organisms?

Back

Decomposing organisms release carbon back into the soil and atmosphere, completing the carbon cycle.

Front

What are fossil fuels?

Back

Fossil fuels are natural substances formed from the remains of ancient organisms, containing stored carbon.

Front

How does carbon dioxide affect climate change?

Back

Increased levels of carbon dioxide in the atmosphere contribute to the greenhouse effect, leading to global warming.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants use sunlight to convert carbon dioxide and water into glucose and oxygen.

Front

What is respiration in the context of the carbon cycle?

Back

Respiration is the process by which living organisms convert glucose and oxygen into energy, releasing carbon dioxide back into the atmosphere.

Front

What is the significance of ocean sediments in the carbon cycle?

Back

Ocean sediments act as a long-term carbon sink, storing carbon for thousands of years.
