Where is the largest reservoir (storage area) for the phosphorus cycle?

• rocks and minerals

• fossil fuels

What is the largest reservoir (storage area) for water?

• the ocean

Animals get the most of the nitrogen they need

• by consuming plants or other animals.

• by breathing in atmospheric nitrogen.

• directly from bacteria in the soil.

• from the process of denitrification.

The movements of energy and nutrients through living systems are different because

• energy flows in one direction, and nutrients recycle.

• energy is limited in the biosphere, and nutrients are always available.

• nutrients flow in one direction, and energy recycles.

• energy forms chemical compounds, and nutrients are lost as heat.

Which process takes Carbon Dioxide from the air and converts it into a form of carbon used by living things?

• Precipitation

• Photosynthesis

• Cellular Respiration

• Transpiration
