Front

What is the carbon cycle?

Back

The movement of carbon through different ecosystems.

Front

Front

What is the main source of carbon dioxide in the atmosphere?

Back

Burning fossil fuels.

Front

Back

Sunlight.

Front

Define biogeochemical cycles.

Back

Natural processes that recycle nutrients in various chemical forms from the environment to living organisms and back to the environment.

Front

What role do plants play in the carbon cycle?

Back

Plants absorb carbon dioxide during photosynthesis, converting it into organic matter.

Front

Explain the process of evaporation in the hydrologic cycle.

Back

Evaporation is the process where water changes from liquid to vapor, rising into the atmosphere.

Front

What is transpiration?

Back

Transpiration is the process by which water is absorbed by plant roots and released as vapor through pores in leaves.

Front

How does the carbon cycle affect climate change?

Back

Increased carbon dioxide levels from human activities enhance the greenhouse effect, leading to global warming.
