What is life?
 
The ability to manipulate energy
2
What are the two sources of energy?

3
What is the equation for photosynthesis?
 
co2+h20 ----> c6h1206+02
4
What is chemosynthesis?

What are phytoplankton?
 
Drifting photosynthesizing organisms
8
What are extremophiles?
 
Single cell organisms that live in the extreme environments such as vents, salt ponds, etc.
9
What family are extremophiles in?
 
archae family
10
What are trophic levels?
 
groups that are defined by their mode of feeding
11
What are the two trophic levels?
 
1. Autotrophs- Primary producer, self feeder
2. Heterotrophs- Consumer
12
What is the correlation between number of organisms to the trophic level?
 
There are more primary producers than anything else and there are a limited number of top level...
13
What 4 elements make up life?
 
1. Nitrogen
2. Oxygen
3. Hydrogen
4. Carbon
14
What are biochemical cycles?
 
 The interaction of living and non-living trophic levels
15
What are limiting factors?
 
A physical or biological necessity that limits action of organisms
16
What are some good examples of limiting factors?
 
1. Temperature
2. Light
3. Nutrients
17
What is the limiting factor in the aphotic zone? 
 
Light
18
What are ectothermic organisms?
 
Organisms that are cold blooded. Have an external heat source
19
What are endothermic organisms?
 
Warm blooded organisms. Have an internal heat source
20
What are the factors affecting functions of organisms?
 
1. Light
2. Temperature
3. Nutrients
4 . Salinity
5. Dissolved Gasses
21
The solubility of gasses in water _____ as temperature _____
 
Decreases; Increases
22
What is diffusion?
 
The spread of something due to the random vibration of molecules that causes an equal diffusion...
23
What is osmosis?
 
The diffusion of water through a membrane into a solution where the solvent concentration is higher, thus equalizing theconcentrations of materials on either side of themembrane.
24
What is active transport?
 
The active movement through a membrane. The reverse of passive diffusion. Requires energy
25
What is evolution?
 
Change over time
26
What is natural selection?
 
The organisms most well adapted to the environment will survive. Environment chooses individuals...
27
Who proposed the theory of natural selection?
 
Charles Darwin
28
What is taxonomy?
 
How we organize living (and dead) organisms
29
What are the two types of cells?
 
1. Prokaryote
2. Eukaryote
30
What are prokaryote and eukaryote cell types like?
 
Pro- simple, small cells, no nucleus
Euk - bigger, complex with nucleus
31
What are the three domains?
 
1. Bacteric
2. Archaea
3. Eukarya
32
What are the 6 kingdoms?
 
1. Eubacteria
2. Archaebacteria 
3. Fungi
4. Animilia

7....
35
What is a species?
 
A group of individuals with genetic material from the same gene pool that can create offspring...
36
Binomial Nomenclature
 
One standardized Latin word for the genus and for the species
* Genus capitalized
37
What are the two life habit types in the ocean?

41
How do you measure primary productivity?
 
Black and clear water bottles in the different levels of the ocean (euphotic, aphotic, photic...
42
What defines the bottom of the euphotic zone?
 
Where the respiration and photosynthesis levels are equal
43
