Water falling to the earth from condensed clouds is known as what?
Precipitation.
What is wrong with atmospheric nitrogen?
Plants and animals can't use it.
What process do animals use to convert glucose and oxygen into carbon dioxide, water, and chemical energy?
Cellular respiration.
What organisms are the primary user of photosynthesis?
Plants.
Which biological process do plants use to take in carbon dioxide from the atmosphere and get energy?
Photosynthesis.
Once that water falls to the other, what is it considered?
Groundwater.
Who "fixes" the nitrogen into a form that we can use?
Bacteria in the soil.
What type of organisms are at the base of the energy pyramid?
Producers.
What are the reactants or starting materials for photosynthesis?
Carbon dioxide, water, and light.
Name one way that carbon is released into the atmosphere using biological processes?
By cellular respiration or decomposition.
How does ocean/lake water return to the atmosphere?
Evaporation.
Animals get most of the nitrogen they need by what?
Consuming plants or other animals that have the nitrogen.
What diagram describes the flow of energy within a set of organisms?
Food chain.
What are the products of photosynthesis?
Glucose and oxygen.
Humans have contributed more carbon to the carbon cycle by doing what?
By burning fossil fuels.
What is the largest source of evaporation on Earth?
Oceans.
Spreading fertilizer in a field the year before a crop will do what to the productivity of your field?
Increase productivity.
Which organelle conducts cellular respiration?
Mitochondria.
What form of energy do plants store in their bodies?
Chemical energy.
How do herbivores and carnivores get the carbon that they need?
By consuming plants and/or animals that have carbon.
Where does transpiration occur?
In the leaves of plants.
Nitrogen is used in the body to make what?
DNA and proteins.
Where does chemosynthesis take place?
Near hydrothermal vents.
What organelle does photosynthesis take place?
Chloroplast.
Why do we need carbon?
"to form DNA and proteins". The creation of cells is also acceptable.
