1Water Molecule Properties
-Bipolar
-London Dispersion and Dipole Dipole Forces
-Universal Solvent
2Cohesion
-Attraction of water to other water molecules
3Adhesion
Attraction of water molecules to other particles
4Importance of H2O
-Maintains stable heat balanace
-Universal Solvent
-Major component of cells and intercellular/extracellular fluid
-Organisms require water for a stable environment
5Carbon+O2 Cycle
Consists of Cellular Resp and Photosynthesis
6Organic Molecules
Molecules makde of Carbon and Hydrogen
7Carbon Source
Releases Carbon
Volcanoes and Burning Fuel
8Carbon Sink
Carbon is stored
Coal/Petroleum
9What is Nitrogen vital for?
ATP, DNA, Amino Acids
10Nitrogen Fixation
Convers N2 into compounds that are usuable by plants, usually NO3 or NH3
Can be accomplished with lightning or bacteria
11Nitrification
Converts NH3 into NO3
Converts compounds into NO3 so they can be usuable by bacteria
12Denitrification
NO3 breaks down into N2
Often happens in low o2 areas, bacteria uses the 02 for cell resp and photosynthesis
13Legume
Any plant apart of the Fabacae family
(Beans, Lentil, Peas)
14Phosphorus Cycle
Movement of phosphates from earth to organisms and then back around
15What is Phosphorus important for?
-Bones/Teeth
-ATP
-DNA
-Cell Membranes
16Eutrification
Buildup of nutrients in aquatic ecosystems
17Algal Bloom
Overgrowth of microscopic algae in fresh salt or wetland waters
18Long Term Phosphorus Cycle
Rocks -> Ocean Floor/Bones & Teeth -> Weather
19Short Term Phosphorus Cycle
Decomposers -> Phosphates in Soil/Water -> Food Webs
