Nitrogen Cycle
What 2 things can fixate nitrogen from the atmosphere?
Bacteria and Lightening
What is evaporation?
What is the chemical formula for oxygen?
O2
What is the chemical formula for carbon dioxide?
CO2
Where does phosphorus come from?
Weathering or mining of rocks.
What percent of the atmosphere is nitrogen gas?
78%
What is condensation?
Condensation is the process by which water vapor in the air is changed into liquid water.
The breakdown of substances into simpler molecules is called what?
Decomposition
What 2 main substances are burned to release carbon dioxide?
Wood and Fossil Fuels
What is a producer?
An organism that can produce its own food (energy) via photosynthesis.
DAILY DOUBLE
What is ammonification?
DAILY DOUBLE
Ammonification is the process where bacteria or other types of decomposing organisms, break down dead organic matter, into simple substances like ammonia.
What is precipitation?
Precipitation is any liquid or frozen water that forms in the atmosphere and falls to Earth.
Where on Earth is most of the oxygen produced?
The ocean.
Where do plants get carbon dioxide from?
Where and how do plants get phosphorus?
From the soil and by their roots.
What is nitrification?
Nitrification is a bacterial process by which ammonia is oxidized (turned) to nitrite and nitrate.
What is transpiration?
Transpiration is the evaporation of water from plant leaves.
What organism produces most of the oxygen of Earth?
Phytoplankton.
What is respiration?
Exchange of oxygen and carbon dioxide between living cells and their environment is this.
What is sedimentation?
When phosphorus-containing compounds from the bodies or wastes of marine organisms sink to the floor of the ocean or lake, they form new sedimentary layers containing phosphorus.
What is denitrification?
Denitrification is a bacterial process by which nitrates are reduced to gaseous nitrogen.
What is sublimation?
Sublimation is the conversion between the solid and the gaseous phases of matter, with no intermediate liquid stage. The process of snow and ice changing into water vapor (gas) in the air without first melting into water.
What is the formula for photosynthesis?
6CO2+6H2O→C6H12O6+6O2
Carbon Dioxide+Water->Glucose(sugar)+Oxygen
What is the formula for photosynthesis?
6CO2+6H2O→C6H12O6+6O2
Carbon Dioxide+Water->Glucose(sugar)+Oxygen
DAILY DOUBLE
What is fertilizer runoff?
DAILY DOUBLE
Fertilizer runoff is the movement of fertilizer by rainwater and irrigation, from their intended use on a residential or commercial site, to local water sheds and reservoirs. (rivers, lakes, oceans)
