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 biogeochemical systems do to matter within the biosphere?

What is "they transform it", or change what form it comes in.

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 liquid precipitation falls to the ground, what is it considered?

What is groundwater.

200

What "fixes" the nitrogen into a form that we can use?

What is bacteria (either in the soil or in the roots of legumes).

200

Break down the word "biogeochemical cycle" and identify its meaning.

What is "living, Earth, chemical (water, nitrogen, carbon, phosphorus), and change/rotate".

The changes that take place when 'chemicals' rotate between the Earth and living things.

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.

200

Name two ways that carbon is released into the atmosphere using biological processes.

What is cellular respiration and decomposition.

300

How ocean/lake water returns to the atmosphere.

What is evaporation.

300

Animals get most of the nitrogen they need by doing what?

What is "consuming plants or other animals that have the nitrogen".

300

The amount of nutrients (such as nitrogen, oxygen, etc.) within an ecosystem is known as what?

What is nutrient availability.

300

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

What is "the rock must break down".

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"?

What is transpiration.

400

Planting legumes (soybean, clover, etc) 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

How are chemosynthesis and photosynthesis different?

What is "chemosynthesis requires chemical energy to produce food and can happen anywhere; photosynthesis requires sunlight energy to produce food and can only happen where sun can reach it".

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

Nitrogen is used in the body to make what?

What is DNA and proteins.

500

How are chemosynthesis and photosynthesis similar?

What is "they are used by producers (not consumers) and both processes produce carbohydrates and oxygen".

500

Phosphorus is returned to the rock cycle from plants and animals by what?

What is "decomposition".

500

Why do we need carbon?

What is "to form DNA and proteins". The creation of cells is also acceptable.
