EOC Review: Carbon Cycle

Front

What is the carbon cycle?

Back

The carbon cycle is the process by which carbon is exchanged between the Earth's atmosphere, land, water, and living organisms, involving processes like photosynthesis, respiration, and decomposition.

Front

What happens to carbon when fossil fuels are burned?

Back

When fossil fuels are burned, carbon is released into the atmosphere as carbon dioxide.

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, soils, and oceans.

Front

How do plants contribute to the carbon cycle?

Back

Plants absorb carbon dioxide from the atmosphere during photosynthesis, using it to produce oxygen and glucose.

Front

What role do animals play in the carbon cycle?

Back

Animals contribute to the carbon cycle through respiration, where they take in oxygen and release carbon dioxide.

Front

What is decomposition in the context of the carbon cycle?

Back

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

Front

Why is the ocean considered a carbon sink?

Back

The ocean is considered a carbon sink because it absorbs more carbon dioxide from the atmosphere than it releases.

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 global warming and climate change.

Front

What is respiration?

Back

Respiration is the process by which living organisms convert oxygen and glucose into energy, releasing carbon dioxide as a byproduct.

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.
