What is wrong with atmospheric nitrogen?
What is "we can't use it".
100

The chemical and physical processes that break down rock at Earth's surface due to exposure to wind, rain, etc.

Weathering

100
The majority of the phosphorus in the world is stored in what?
What is rocks.
100
Which biological process do plants use to take in carbon dioxide from the atmosphere and get energy?
What is photosynthesis.
200
Once that water falls to the other, what is it considered?
What is groundwater.
200
Who "fixes" the nitrogen into a form that we can use?
What is bacteria (either in the soil or in the roots of legumes).
200
What does biogeochemical cycling allow nutrients to do throughout the biosphere?
What is circulate.
200

A considerable vertical movement of the Earth's crust due to tectonic plate movement. It is one of the primary factors in the formation of mountains and other prominent landscape features.

Geological Uplift

200
Name two ways that carbon is released into the atmosphere using biological processes?
What is cellular respiration and decomposition.
300
How does ocean/lake water return to the atmosphere?
What is evaporation.
300
Animals get most of the nitrogen they need by what?
What is "consuming plants or other animals that have the nitrogen".
300

____________ is the process where bacteria in the soil turn nitrates back into nitrogen gas, which then leaves the soil and goes back into the atmosphere.

Denitrification

300
What must happen to the rock in order for plants to absorb the phosphorus within them?
What is break down into soil.
300
Humans have contributed more carbon to the carbon cycle by doing what?
What is burning fossil fuels.
400

Water that does not get absorbed by the ground and flows over an impermeable surface is known as

Runoff

400
Planting legumes in a field the year before a crop will do what to the productivity of your field?
What is "increase productivity because there is more nitrogen in the soil".
400

Eutrophication is most closely associated with which of the following nutrient cycles?

Nitrogen and Phosphorus

400
Herbivores and carnivores obtain phosphorus by doing what?
What is "consuming plants and/or animals that have phosphorus".
400
How do herbivores and carnivores get the carbon that they need?
What is "by consuming plants and/or animals that have carbon".
500
What is "transpiration"?
What is "when leaves release water through their underside to evaporate".
500

The process by which bacteria in the soil convert ammonia into nitrite and then into nitrate

Nitrification

500

What is the term for when solar radiation is trapped by to many gases such as carbon dioxide in the atmosphere

The Greenhouse Effect
