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 and oxygen.

Front

What is respiration in the context of the carbon cycle?

Back

Respiration is the process by which animals and plants take in oxygen and release carbon dioxide as they convert glucose into energy.

Front

How do trees contribute to the carbon cycle?

Back

Trees absorb carbon dioxide from the atmosphere during photosynthesis, helping to reduce the amount of CO2 in the air.

Front

What is deforestation?

Back

Deforestation is the large-scale clearing of forests, which reduces the number of trees that can absorb carbon dioxide, contributing to increased atmospheric CO2 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, which release carbon dioxide when burned.

Front

Why is burning fossil fuels harmful to the environment?

Back

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

Front

What role do oceans play in the carbon cycle?

Back

Oceans absorb 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 greenhouse effect?

Back

The greenhouse effect is the warming of the Earth's surface due to the trapping of heat by greenhouse gases like carbon dioxide in the atmosphere.

Front

What is a carbon sink?

Back

A carbon sink is a natural or artificial reservoir that absorbs more carbon than it releases, such as forests, oceans, and soil.
