What is life?
|
The ability to manipulate energy
|
What are the two sources of energy?
|
1. Photosynthesis
2. Chemosynthesis |
What is the equation for photosynthesis?
|
Co2+h20 ----> c6h1206+02
|
What is chemosynthesis?
|
Co2+o2+h2s ---> c6h1206+s+h20
|
Where is chemosynthesis found?
|
Found in the deep ocean, sea floor vents
|
What is primary productivity?
|
Converting energy into usable energy
|
What are phytoplankton?
|
Drifting photosynthesizing organisms
|
What are extremophiles?
|
Single cell organisms that live in the extreme environments such as vents, salt ponds, etc.
|
What family are extremophiles in?
|
Archae family
|
What are trophic levels?
|
Groups that are defined by their mode of feeding
|
What are the two trophic levels?
|
1. Autotrophs- Primary producer, self feeder
2. Heterotrophs- Consumer |
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 trophic groups because they take so much energy to sustain them
|
What 4 elements make up life?
|
1. Nitrogen
2. Oxygen 3. Hydrogen 4. Carbon |
What are biochemical cycles?
|
The interaction of living and non-living trophic levels
|
What are limiting factors?
|
A physical or biological necessity that limits action of organisms
