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.

Front

How do plants contribute to the carbon cycle?

Back

Plants absorb carbon dioxide from the atmosphere during photosynthesis and convert it into glucose, releasing oxygen as a byproduct.

Front

What role do animals play in the carbon cycle?

Back

Animals consume plants and other animals, releasing carbon dioxide back into the atmosphere through respiration.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants use sunlight, carbon dioxide, and water to produce 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 and water as byproducts.

Front

What is a carbon sink?

Back

A carbon sink is a natural or artificial reservoir that absorbs and stores carbon from the atmosphere, such as forests, oceans, and soil.

Front

What is a carbon source?

Back

A carbon source is a process or activity that releases carbon into the atmosphere, such as burning fossil fuels or deforestation.

Front

Why are plants considered essential for life on Earth?

Back

Plants produce oxygen through photosynthesis, which is essential for the survival of most living organisms, including humans.

Front

What happens to carbon in dead organisms?

Back

When organisms die, their carbon is released back into the environment through decomposition, contributing to the carbon cycle.

Front

How does human activity impact the carbon cycle?

Back

Human activities, such as burning fossil fuels and deforestation, increase the amount of carbon dioxide in the atmosphere, disrupting the natural balance of the carbon cycle.
