• Reducing the amount of carbon in the soil

• Absorbing CO2 from the atmosphere, lowering atmospheric levels of carbon

• None of the above; plants do not affect the carbon cycle

The burning of fossil fuels contributes to the carbon cycle in what way?

• Increases the amount of CO2 in the atmosphere

• Increases the amount of O2 in the atmosphere

• Decreases the amount of CO2 in the atmosphere

• Decreases the amount of O2 in the atmosphere

Examples of decomposers include:

• humans, dogs, and whales

• trees, tomato plants, and phytoplankton

• viruses

• fungi, worms, and bacteria

Which of these is NOT a part of the Nitrogen Cycle?

Deforestation affects the Carbon Cycle by...

• Reducing the amount of CO2 that can be removed from the air by plants

• Increasing the amount of CO2 that can be removed from the air by plants

• Increasing the rate of photosynthesis that can be done by plant plants
