Water falling to the earth from condensed clouds is known as what?
What is precipitation.
100

What is the biggest difference between atmospheric nitrogen and other forms of nitrogen that we find in the soil?

What is "we can't use it".

100

What happens to elements (e.g. carbon, nitrogen, phosphorus) as they go through their biogeochemical cycle?

What is they become part of different molecules and move to different parts of the environment.

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

Water that doesn't infiltrate the soil and instead runs along hard surfaces or saturated soil.

What is runoff.

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 (the part of earth containing living things)?

What is circulate or move around to different parts.

200

Phosphorus is available to living organisms in the form of which molecule?

What is phosphate (PO43-).

200

What is the process called where plants release carbon dioxide back into the atmosphere while they process the sugars their formed during photosynthesis?

What is cellular respiration.

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

When water first goes into the soil from the surface, it is called what?

What is infiltration.

300

What must happen to the rock in order for plants to absorb the phosphorus within them?

What is break down into soil through weathering/erosion.

300
Humans have contributed more carbon to the carbon cycle by doing what?
What is burning fossil fuels.
400

Which process within the water cycle is considered "biological" (done by living things)?

What is transpiration.

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

Besides bacteria, what other process can fix nitrogen naturally?

What is lightening.

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 plants release water through the underside of their leaves to evaporate".

500

The process of ammonium being converted to nitrite, or the process of nitrite being converted to nitrate, is called what?

What is nitrification.

500

When carbon dioxide is dissolved in the ocean to form carbonic acid, it does water to the ocean water?

What is "makes it more acidic".

500

What happens when too much phosphorus is added to a body of water?

What is "eutrophication, where lots of growth (especially of algae) is followed by those organisms dying and a lack of oxygen as decomposers break them down".

500

The majority of the world's carbon is stored where?

What is "in rocks and sediments".
