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, and combustion.

What happens to carbon when fossil fuels are burned?

Back

When fossil fuels are burned, carbon is released into the atmosphere in the form of carbon dioxide.

Front

How do plants contribute to the carbon cycle?

Back

Plants take in carbon dioxide from the atmosphere during photosynthesis and release oxygen, thus playing a crucial role in the carbon cycle.

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 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 back into the atmosphere.

Front

Define combustion.

Back

Combustion is a chemical process in which a substance reacts with oxygen to produce heat and light, commonly referred to as burning.

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 a carbon sink?

Back

A carbon sink is a natural or artificial reservoir that accumulates and stores carbon-containing chemical compounds for an indefinite period.

Front

What is the significance of the greenhouse effect in relation to carbon dioxide?

Back

The greenhouse effect is the warming of the Earth's surface due to the trapping of heat by greenhouse gases like carbon dioxide, which can lead to climate change.

Front

How does deforestation impact the carbon cycle?

Back

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