TEST - 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

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 role do producers play in the carbon cycle?

Back

Producers, such as plants, take in carbon dioxide from the atmosphere and convert it into organic matter through photosynthesis.

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.

Front

How do decomposers contribute to the carbon cycle?

Back

Decomposers break down dead organic matter, returning carbon to the soil and atmosphere, thus completing the cycle.

Front

What happens to carbon when an organism dies?

Back

When an organism dies, its carbon is released into the soil or atmosphere through decomposition or can be buried and transformed into fossil fuels.

Front

What are fossil fuels?

Back

Fossil fuels are natural substances formed from the remains of ancient plants and animals, containing stored carbon that can be burned for energy.

Front

What is the significance of carbon dioxide in the carbon cycle?

Back

Carbon dioxide is a key greenhouse gas that plants use during photosynthesis, and it is also released during respiration and combustion.

Front

What is the impact of burning fossil fuels on the carbon cycle?

Back

Burning fossil fuels releases large amounts of carbon dioxide into the atmosphere, contributing to climate change and disrupting the natural carbon cycle.

Front

What is the role of the ocean in the carbon cycle?

Back

The ocean absorbs carbon dioxide from the atmosphere and stores it, playing a crucial role in regulating global carbon levels.
