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 biogeochemical systems do to matter within the biosphere?
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 liquid precipitation falls to the ground, what is it considered?
What is groundwater.
What "fixes" the nitrogen into a form that we can use?
What is bacteria (either in the soil or in the roots of legumes).
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.
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.
How ocean/lake water returns to the atmosphere.
What is evaporation.
Animals get most of the nitrogen they need by doing 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 "the rock must break down".
Humans have contributed more carbon to the carbon cycle by doing what?
What is burning fossil fuels.
Which process within the water cycle is considered "biological"?
What is transpiration.
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".
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 "decomposition".
Why do we need carbon?
What is "to form DNA and proteins". The creation of cells is also acceptable.
