B-LS2-5 Carbon Cycle

Front

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 such as photosynthesis, respiration, decomposition, and combustion.

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 and releasing oxygen.

Front

How do animals contribute to the carbon cycle?

Back

Animals contribute to the carbon cycle by consuming plants and other animals, and by releasing carbon dioxide back into the atmosphere through respiration and decomposition.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy, usually from the sun, into chemical energy in the form of glucose, using carbon dioxide and water.

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 and water as byproducts.

Front

What are carbon reservoirs?

Back

Carbon reservoirs are natural systems that store carbon, such as forests, oceans, soil, and fossil fuels.

Front

What is decomposition?

Back

Decomposition is the process by which organic matter is broken down by microorganisms, returning carbon to the atmosphere and enriching the soil.

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 and disrupting the natural balance of the carbon cycle.

Front

What is the equation for photosynthesis?

Back

The equation for photosynthesis is: CO2 + light + H2O → O2 + Sugar.

Front

How does carbon move through the food chain?

Back

Carbon moves through the food chain when animals consume plants (which contain carbon) and then are consumed by other animals, transferring carbon through the ecosystem.
