Water Cycle
Water falling to the earth from condensed clouds is known as what?
What is precipitation.
What is wrong with atmospheric nitrogen?
What is "we can't use it".
What do biological systems do to matter within the biosphere, allowing matter to recycle?
What is "they transform it", or change what form it comes in.
The majority of the phosphorus in the world is stored in what?
What is rocks.
Which biological process do plants use to take in carbon dioxide from the atmosphere and get energy?
What is photosynthesis.
Once that water falls to the other, what is it considered?
What is groundwater.
Who "fixes" the nitrogen into a form that we can use?
What is bacteria (either in the soil or in the roots of legumes).
What does biogeochemical cycling allow nutrients to do throughout the biosphere?
What is circulate.
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.
Name two ways that carbon is released into the atmosphere using biological processes?
What is cellular respiration and decomposition or ocean/atmosphere gas exchange.
How does ocean/lake water return to the atmosphere?
What is evaporation.
Animals get most of the nitrogen they need by what?
What is "consuming plants or other animals that have the nitrogen".
The amount of nutrients (such as nitrogen, oxygen, etc.) within an ecosystem is known as what?
What is nutrient availability.
What must happen to the rock in order for plants to absorb the phosphorus within them?
What is break down into soil.
Humans have contributed more carbon to the carbon cycle by doing what?
What is burning fossil fuels, respiration.
What process, in trees, accounts for most of the water in the atmosphere over land?
What is transpiration.
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".
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".
Herbivores and carnivores obtain phosphorus by doing what?
What is "consuming plants and/or animals that have phosphorus".
How do herbivores and carnivores get the carbon that they need?
What is "by consuming plants and/or animals that have carbon".
What is "transpiration"?
What is "when leaves release water through their underside to evaporate".
Nitrogen is used in the body to make what?
What is DNA and proteins.
How are chemosynthesis and photosynthesis similar?
What is "they are used by producers (not consumers) and both processes produce carbohydrates and oxygen".
Phosphorus is returned to the rock cycle from plants and animals by what?
What is "hardening into solid phosphate after being sediment".
Why do we need carbon?
What is "to form DNA and proteins". The creation of cells is also acceptable.
