Characteristic
Moving Stream
Water layered by temperature
Higher levels of dissolved oxygen
Higher salt content
Occurrence of eutrophication
Many anaerobic organisms
Many aerobic organisms
Lake or Pond

3. The Nitrogen Cycle
_____ Ammonification
_____ Denitrification
_____ Nitrification
_____ Nitrogen Fixation
a. Conversion of ammonia to usable nitrates
b. Bacteria on plant roots convert N2 gas to ammonia
c. Conversion of unused nitrates back to N2 gas
d. Bacteria produces ammonia from nitrogenous wastes
4. Energy flows through and ecosystem, matter is cycled (often by bacteria). No question here, just a reminder
comment!
5.

b. Which organisms here feed at multiple
trophic levels?
c. Why are there usually only around 4 trophic
levels in a food chain?
