Water falling to the earth from condensed clouds is known as what?
What is precipitation.
100
What is wrong with atmospheric nitrogen?
What is "we can't use it".
100

What do the word parts of the biogeochemical cycle stand for? (bio, geo, chemical)

What is bio = life, geo = earth, chemical = pertaining to chemistry

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

When liquid water turns into water vapor, what is that called?

What is evaporation

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

Phosphorus is used not only in energy and in cell processes (like enzymes and transport), but also in what?

What is forming DNA and RNA, cell membranes, growth and development, and/or bones and teeth.

200

Name two ways that carbon is returned to the environment?

What is cellular respiration, decomposition, combustion, and/or ocean absorption.

300

How do humans harm or alter the water cycle? (list one way)

What is pollution, land development, deforestation, etc.

300
Animals get most of the nitrogen they need by what?
What is "consuming plants or other animals that have the nitrogen".
300

When a nutrient (such as nitrogen, oxygen, etc.) constrains or restricts an organisms population size, it is called a what?

what is a limiting factor

300

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

What is broken down into soil by erosion?

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

What is it called after water precipitates and it flows across the land surface to storage?

What is 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

Describe the law conservation of mass

What is "matter is neither created, nor destroyed"

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 "a special type of evaporation that occurs through the surface of plants (ex. plant leaves)".

500
Nitrogen is used in the body to make what?
What is DNA and proteins.
500
Describe why biogeochemical cycles are important for life.

Matter is neither created nor destroyed, so we must recycle matter so new organisms have access to nutrients.

500

Phosphorus is returned to the rock cycle (long-term cycle) from plants and animals by what?

What is "hardening into solid phosphate after being sediment".

500
Why do we need carbon?
What is "to form DNA and proteins". The creation of cells is also acceptable.
