Carbon Cycle

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, and combustion.

What is combustion?

Back

Combustion is a chemical reaction that occurs when a substance (usually a fossil fuel) reacts with oxygen to produce heat and light, resulting in the release of carbon dioxide.

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?

Back

Respiration is the process by which living organisms convert glucose and oxygen into energy, producing carbon dioxide and water as byproducts.

Front

What are fossil fuels?

Back

Fossil fuels are natural substances formed from the remains of ancient plants and animals, including coal, oil, and natural gas, that can be burned for energy.

Front

What is a carbon sink?

Back

A carbon sink is a natural or artificial reservoir that absorbs more carbon dioxide from the atmosphere than it releases, helping to reduce the concentration of CO2.

Front

How do humans impact the carbon cycle?

Back

Humans impact the carbon cycle primarily through the burning of fossil fuels, which increases the amount of carbon dioxide in the atmosphere.

Front

What is the role of plants in the carbon cycle?

Back

Plants play a crucial role in the carbon cycle by absorbing carbon dioxide during photosynthesis and releasing oxygen.

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 decomposition?

Back

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