ENVS LT 2.3: Carbon Cycle Review

The four spheres through which carbon moves in the carbon cycle are:

• atmosphere, biosphere, hydrosphere, geosphere

• atmosphere, stratosphere, lithosphere, mesosphere

• hydrosphere, troposphere, exosphere, biosphere

• geosphere, ionosphere, hydrosphere, thermosphere

Photosynthesis plays which role in the carbon cycle?

• It removes carbon dioxide from the atmosphere and converts it into organic compounds.

• It releases carbon dioxide into the atmosphere through respiration.

• It breaks down organic matter to release carbon dioxide.

• It increases the amount of carbon dioxide in the atmosphere by burning fossil fuels.

Respiration contributes to the carbon cycle by:

• releasing carbon dioxide into the atmosphere

• absorbing carbon dioxide from the atmosphere

• converting carbon dioxide into oxygen

• removing carbon from fossil fuels

The burning of fossil fuels affects the carbon cycle by:

• increasing the amount of carbon dioxide in the atmosphere

• decreasing the amount of carbon dioxide in the atmosphere

• removing carbon dioxide from the atmosphere completely

• having no effect on atmospheric carbon dioxide
