Water Cycle
100

This process converts carbon dioxide into organic matter using sunlight

Photosynthesis 

100

This process converts atmospheric nitrogen into a usable form for plants

Nitrogen fixation

100

Phosphorus is primarily found in this type of rock

Sedimentary rock

100

This process involves the transition of water from liquid to vapor

Evaporation

200

Name the gas released during cellular respiration

Carbon dioxide (CO2)

200

What is the process called when bacteria convert nitrates back into nitrogen gas?

Denitrification

200

This process describes the movement of phosphorus through soil, water, and living organisms

Phosphorus cycle

200

What is the term for the movement of water through soil?

Infiltration

300

This term describes the long-term storage of carbon in the earth's crust

Fossil fuels 

300

Name the organisms that perform nitrogen fixation

Nitrogen-fixing bacteria

300

What is the main form of phosphorus that plants can absorb?

Phosphate

300

This is the process by which plants release water vapor into the atmosphere

Transpiration

400

What is the primary human activity contributing to increased carbon dioxide levels?

Burning of Fossil Fuels

400

This term refers to the conversion of ammonia into nitrates

Nitrification

400

This human activity can lead to excessive phosphorus runoff into water bodies

Agricultural runoff

400

Name the stage in the water cycle where water falls to the earth as rain, snow, or sleet

Precipitation

500

This biome is known for its significant carbon storage due to large amounts of vegetation

Forests

500

What is the primary source of nitrogen in fertilizers?

Synthetic fertilizers

500

Unlike carbon and nitrogen, phosphorus does not have a significant atmospheric component. True or False?

True

500

This term describes the continuous movement of water through the environment
