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 and some other organisms use sunlight to synthesize foods with the help of carbon dioxide and water, releasing oxygen as a byproduct.

Front

What is respiration in the context of the carbon cycle?

Back

Respiration is the process by which living organisms take in oxygen and release carbon dioxide as they convert food into energy.

Front

What role do decomposers play in the carbon cycle?

Back

Decomposers break down dead organic matter, returning carbon to the soil and atmosphere, and making nutrients available for plants.

Front

What are fossil fuels?

Back

Fossil fuels are natural substances formed from the remains of ancient plants and animals, buried and subjected to heat and pressure over millions of years, which can be burned for energy.

Front

How do plants contribute to the carbon cycle?

Back

Plants absorb carbon dioxide from the atmosphere during photosynthesis and release oxygen, thus playing a crucial role in regulating atmospheric carbon levels.

Front

What is the significance of carbon dioxide in the atmosphere?

Back

Carbon dioxide is a greenhouse gas that traps heat in the atmosphere, contributing to the greenhouse effect and climate change.

Front

What happens to carbon in dead organisms?

Back

When organisms die, their carbon is released back into the environment through decomposition or can be buried and transformed into fossil fuels.

Front

What is the difference between primary and secondary consumers?

Back

Primary consumers are herbivores that eat producers (plants), while secondary consumers are carnivores that eat primary consumers.

Front

What is combustion?

Back

Combustion is the process of burning fossil fuels or organic matter, which releases carbon dioxide and other gases into the atmosphere.
