- produce carbohydrates from energy from inorganic molecules
- food web
- interrelated food chains
- benthic zone
- ocean bottom
- consumers
- hetrotrophs
- character displacement
- niche differences lessen competition
- ground water
- water in soil/underground
- denitrification
- when nitrogen is returned to atmosphere
- eutrophic lakes

- forested evergreen trees- long winters short summers
- asthenosphere
- in mantel, below lithosphere consist of slowing flowing rock
- nitricifcation
- when bacteria in soil takes up ammonia and oxidizes it into nitrtes
- lithosphere
- thin outer shell of earth, oceanic/surface crust+upper mantle
- dormancy
- organism becomes less active
- photic zone
- ocean receives sunlight
- isobar
- line on weather map connecting points of equal pressure

- trophic level
- indicates organisms postition in engeryg food levels (pyramid)
- nitrogen-fixing bacteria
- they convert nitrogen to ammonia, which plants then use to make protien
