Carbon Cycle

Front

What is the carbon cycle?

Back

The carbon cycle is the process by which carbon is exchanged among the atmosphere, land, water, and living organisms. It involves processes like photosynthesis, respiration, decomposition, and combustion.

Front

Why is the carbon cycle important?

Back

The carbon cycle is crucial for maintaining the balance of carbon in the environment, supporting life by regulating climate, and providing essential nutrients for plants and animals.

Front

What role do plants play in the carbon cycle?

Back

Plants absorb carbon dioxide from the atmosphere during photosynthesis, converting it into organic matter and releasing oxygen.

Front

What are decomposers?

Back

Decomposers are organisms, such as bacteria and fungi, that break down dead organic matter, recycling nutrients back into the ecosystem.

Front

How do animals obtain carbon?

Back

Animals obtain carbon by consuming plants and other animals, incorporating carbon into their bodies.

Front

What is combustion?

Back

Combustion is a chemical reaction that occurs when a substance reacts with oxygen, producing heat and light, and often releasing carbon dioxide.

Front

What is the greenhouse effect?

Back

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

Front

What are fossil fuels?

Back

Fossil fuels are natural substances formed from the remains of ancient plants and animals, primarily composed of carbon, and used as energy sources.

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.
