Front

What is the process of carbon moving from the hydrosphere to the biosphere?

Back

Aquatic plants absorb carbon dioxide from water during photosynthesis.

Front

What happens to carbon when humans burn fossil fuels?

Back

Most of the carbon quickly enters the atmosphere as carbon dioxide.

Front

Which activity does not contribute to CO2 emissions?

Back

Planting trees does not add CO2 to the atmosphere.

Front

What are fossil fuels?

The biosphere is the global sum of all ecosystems, where life exists on Earth.

Front

Explain the carbon cycle.

Back

The carbon cycle is the process by which carbon is exchanged among the biosphere, geosphere, hydrosphere, and atmosphere.

Front

What role do decomposers play in the carbon cycle?

Back

Decomposers break down dead organic matter, releasing carbon back into the soil and atmosphere.

Front

How do plants contribute to the carbon cycle?

Back

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