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 various processes such as photosynthesis, respiration, decomposition, and combustion.

Front

Where can carbon be found?

Back

Carbon can be found in the atmosphere, soil, fossil fuels, and living organisms.

Front

What process removes carbon dioxide from the atmosphere?

Back

Photosynthesis removes carbon dioxide from the atmosphere as plants convert it into glucose and oxygen.

Front

What happens when humans burn fossil fuels?

Back

When humans burn fossil fuels, carbon is released into the atmosphere as carbon dioxide, contributing to climate change.

Front

What role do decomposers play in the carbon cycle?

Back

Decomposers break down dead plants and animals, returning carbon to the soil and atmosphere.

Front

What is respiration in the context of the carbon cycle?

Back

Respiration is the process by which animals and plants take in oxygen and release carbon dioxide as a byproduct of energy production.

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

How does carbon enter the atmosphere?

Back

Carbon enters the atmosphere through processes like combustion of fossil fuels, respiration, and volcanic eruptions.

Front

What is the significance of carbon in living organisms?

Back

Carbon is a fundamental building block of life, forming the backbone of organic molecules such as carbohydrates, proteins, and fats.

Front

What is a carbon sink?

Back

A carbon sink is a natural or artificial reservoir that absorbs more carbon than it releases, such as forests, oceans, and soil.
