Carbon Cycle Flashcard

Front

What does it mean to be a "greenhouse gas"?

Back

A greenhouse gas can trap heat in the atmosphere, leading to global warming.

Front

Which process does CO2 go through for plants to convert it to O2?

Back

Photosynthesis.

Front

Where is carbon stored in the environment?

Back

In the atmosphere and water.

Front

What does the "C" stand for in CO2?

Back

Carbon.

Front

What pathway does CO2 take?

Back

CO2 -> Plants -> Animals -> CO2.

Front

What is the role of photosynthesis in the carbon cycle?

Back

Photosynthesis allows plants to convert CO2 into oxygen and glucose.

Front

What is respiration in the context of the carbon cycle?

Back

Respiration is the process by which animals and plants convert glucose and oxygen into energy, releasing CO2.

Front

How do human activities affect the carbon cycle?

Back

Human activities, such as burning fossil fuels, increase CO2 levels in the atmosphere.

Front

What is the significance of carbon sinks?

Back

Carbon sinks, like forests and oceans, absorb more CO2 than they release, helping to mitigate climate change.

Front

What is the difference between carbon sources and carbon sinks?

Back

Carbon sources release more CO2 than they absorb, while carbon sinks absorb more CO2 than they release.
