Front

Plants use carbon dioxide in the process of _____________.

Back

Photosynthesis.

Front

How does increasing CO2 concentration affect average global temperature?

Back

As CO2 concentration increases, average global temperature increases.

Front

Which of the following adds carbon dioxide to the atmosphere?

Back

Volcanoes, combustion of fossil fuels, and animal and plant respiration all add carbon dioxide to the atmosphere.

Front

Is the total amount of carbon on Earth constant?

Back

True, the total amount of carbon on Earth is constant.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which plants use sunlight to convert carbon dioxide and water into glucose and oxygen.

Front

What role do volcanoes play in the carbon cycle?

Back

Volcanoes release carbon dioxide into the atmosphere during eruptions.

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 greenhouse effect?

Back

The greenhouse effect is the warming of Earth's surface due to the trapping of heat by greenhouse gases like carbon dioxide.

Front

What is the significance of carbon sinks?

Back

Carbon sinks are natural systems that absorb more carbon than they release, helping to reduce the amount of CO2 in the atmosphere.
