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 process do plants use to absorb carbon dioxide from the atmosphere?

Back

Photosynthesis is the process by which plants and algae absorb carbon dioxide from the atmosphere and convert it into glucose and oxygen using sunlight.

Front

How do animals contribute to the carbon cycle?

Back

Animals contribute to the carbon cycle primarily through respiration, where they inhale oxygen and exhale carbon dioxide, returning carbon to the atmosphere.

Front

What happens to carbon when fossil fuels are burned?

Back

When fossil fuels are burned, carbon stored in these fuels is released into the atmosphere as carbon dioxide, contributing to greenhouse gas emissions.

Front

What is the role of decomposition in the carbon cycle?

Back

Decomposition is the process by which dead organic matter is broken down by microorganisms, releasing carbon back into the soil and atmosphere.

Front

How does deforestation affect the carbon cycle?

Back

Deforestation reduces the number of trees available to absorb carbon dioxide through photosynthesis, leading to an increase in atmospheric carbon levels.

Front

What are fossil fuels?

Back

Fossil fuels are natural substances like coal, oil, and natural gas formed from the remains of ancient plants and animals over millions of years.

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 as a waste product.

Front

How does the ocean play a role in the carbon cycle?

Back

The ocean absorbs a significant amount of carbon dioxide from the atmosphere, acting as a carbon sink and helping to regulate global carbon levels.

Front

What is the impact of increased carbon dioxide levels in the atmosphere?

Back

Increased carbon dioxide levels contribute to global warming and climate change by enhancing the greenhouse effect.
