Water Cycle
Phosphorus Cycle
Nitrogen Cycle
Carbon Cycle
Oxygen Cycle
100
Another name for the water cycle.
What is the hydrologic-cycle?
100
Wastes from living things are recycled in the short term cycle by this type of organism.
What are decomposers?
100
The percentage of Nitrogen gas that makes up the Earth's atmosphere.
What is 79%?
100
When not in organic form carbon is found in these three main reservoirs.
What is the atmosphere, oceans, and the Earth's crust?
100
Oxygen may be found in any of these four places.
What is water, the atmosphere, rocks, and living things?
200
Examples of this process are sleet and hail.
What is precipitation?
200
Reason why phosphorus is difficult for plants and animals to reach?
What are phosphorus reservoirs? (rocks)
200
Plants absorb nitrogen in order to carry out this action.
What is building proteins?
200
Carbon Dioxide is taken out of the atmosphere through this process.
What is photosynthesis?
200
The two chemical processes that are apart of both the carbon and oxygen cycles.
What is photosynthesis and cellular respiration?
300
Results in precipitation.
What is the process in which air currents are no longer able to support the mass of droplets or ice crystals anymore.
300
Sphere in which phosphorus does not travel through.
What is the atmosphere?
300
The function of nitrifying bacteria.
What is the conversion of ammonia into nitrates?
300
The Earth's largest reservoir of carbon.
What are sedimentary rocks?
300
Where most of the Earth's oxygen is stored.
What is the lithosphere (rocks)?
400
The process of the water cycle that helps in transporting phosphorus from land to water bodies.
What is runoff?
400
Phosphorus is needed for the production of these in humans.
What are phospholipids, DNA and RNA, bones, and ATP.
400
The conditions where denitrifying bacteria works the best (think of aerating lawns).
What is the lack of oxygen?
400
Most of the carbon in living organisms is returned to atmosphere in this form.
What is carbon dioxide?
400
The main driving force of the oxygen cycle (in terms of chemical processes).
What is photosynthesis?
500
Living organisms may return removed water back into environment through this process.
What is cellular respiration or (decay of dead animals)?
500
Reason why phosphorus is unable to be found in atmosphere.
Phosphorus is at liquid state under normal temperature and pressure.
500
Reason why Nitrogen gas- N2 is useless to plants.
Nitrogen gas is a stable molecule and will only react under limited conditions which is why it must be converted to a nitrate ion.
500
The only process through which carbon in fossil fuels and rocks may be returned to the atmosphere.
What is combustion?
500
Reason why amount of carbon dioxide introduced into the atmosphere greater than the amount of oxygen used during aerobic respiration?
What is the release of carbon dioxide through decomposers, and burning fossil fuels and forests?
