Water Cycle
This percent of water is stored in oceans
What is 97%?
The Process animals use to make more carbon dioxide
What is respiration?
Animals and plants cannot directly use nitrogen from this
What is the atmosphere?
Places where phosphorus are found
What are rocks and minerals?
With ample amount of sun, the limit to productivity is this
What is nutrients?
Process in which turns into a gas to be stored in the atmosphere in the form of clouds
What is evaporation?
A natural source for carbon dioxide
What is a volcano?
This is the product of animal waste decay by the action of bacteria
What is ammonia and nitrate?
Places where phosphorus moves in the phosphorus cycle
What is the soil and plants?
A nutrient where whose supply limits productivity is soil
What is a limiting nutrient?
A place where water runoff is dispersed
What are Oceans, lakes, rivers?
Plants use Carbon Dioxide in this process to make sugar and oxygen
What is photosynthesis?
Our atmosphere is made up of this percent of nitrogen gas
What is 78% nitrogen gas?
too much phosphorus in water leads to this
What is overgrowth?
In aquatic areas, normally nitrogen is limited in this area
What are oceans?
The process in which water condenses to form clouds
What is condensation?
More Carbon dioxide is released into the atmosphere today because of this process
What is the burning of fossil fuels?
This is what higher organisms Nitrogen to make?
What are proteins?
What are basins?
In aquatic areas, phosphorus is limiting in this area
What is freshwater?
Water falls onto the surface as is
What is precipitation?
An effect that occurs when there is too much carbon dioxide in the air
What is the greenhouse effect?
Bacteria that can directly use nitrogen in our atmosphere and fix it for other organisms benefit
What are nitrogen-fixing bacteria?
phosphorus makes up this important chemical
These are examples of limiting nutrients
What are nitrogen, phosphorus, potassium, and micronutrients?
