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 happens when humans burn fossil fuels?

Back

When humans burn fossil fuels, carbon is released into the atmosphere as carbon dioxide, contributing to climate change.

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 role do trees play in 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 respiration in animals?

Back

Respiration is the process by which animals take in oxygen and release carbon dioxide as a byproduct.

Front

What is combustion?

Back

Combustion is a chemical process that occurs when a substance (like coal or fossil fuels) reacts with oxygen to produce energy, releasing carbon dioxide and other gases.

Front

What is the significance of decomposers in the carbon cycle?

Back

Decomposers break down dead organic matter, returning carbon to the soil and atmosphere, thus playing a crucial role in recycling nutrients.

Front

How does the ocean contribute to 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 climate.

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 the impact of deforestation on the carbon cycle?

Back

Deforestation reduces the number of trees available to absorb carbon dioxide, leading to increased levels of CO2 in the atmosphere.
