Carbon Cycle Flashcard

Front

What are greenhouse gases?

Back

Greenhouse gases are gases in the atmosphere that trap heat energy, contributing to the greenhouse effect and raising the Earth's overall temperature.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which plants convert carbon dioxide (CO2) and sunlight into glucose and oxygen, absorbing CO2 in the process.

Front

Where can carbon be found?

Back

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

Front

Is all carbon in existence recycled in the carbon cycle?

Back

True, all carbon in existence is continually recycled in the carbon cycle.

Front

What role do carbon sinks play in the carbon cycle?

Back

Carbon sinks, such as forests and oceans, absorb more carbon dioxide than they release, helping to mitigate climate change.

Front

What is the significance of fossil fuels in the carbon cycle?

Back

Fossil fuels are carbon-rich energy sources formed from ancient organic matter, and their combustion releases stored carbon back into the atmosphere.

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 as a byproduct.

Front

What is the role of decomposers in the carbon cycle?

Back

Decomposers break down dead organic matter, returning carbon to the soil and atmosphere, thus facilitating the recycling of carbon.

Front

How do human activities impact the carbon cycle?

Back

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

Front

What is the greenhouse effect?

Back

The greenhouse effect is the warming of the Earth's surface due to the trapping of heat by greenhouse gases in the atmosphere.
