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 like photosynthesis, respiration, decomposition, and combustion.

What is photosynthesis?

Back

Photosynthesis is the process by which green plants use sunlight to convert carbon dioxide and water into glucose (sugar) 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 and water as byproducts.

Front

What is the Law of Conservation of Mass?

Back

The Law of Conservation of Mass states that mass cannot be created or destroyed in a chemical reaction; it can only change forms.

Front

How do plants contribute to the carbon cycle?

Back

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

Front

What role do decomposers play in the carbon cycle?

Back

Decomposers break down dead organic matter, returning carbon to the soil and atmosphere, thus recycling nutrients.

Front

What is a carbon reservoir?

Back

A carbon reservoir is a natural feature that stores carbon, such as forests, oceans, soil, and the atmosphere.

Front

How does combustion affect the carbon cycle?

Back

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

Front

What is the significance of carbon dioxide in the atmosphere?

Back

Carbon dioxide is a greenhouse gas that traps heat in the atmosphere, playing a crucial role in regulating Earth's temperature.

Front

What is the role of oceans in the carbon cycle?

Back

Oceans absorb carbon dioxide from the atmosphere and store it, acting as a significant carbon sink.
