Things to remember (Unit 4):
Nitrogen Cycle:

Denitrification ­ Anaerobic. Converts Nitrates to Nitrogen Gas.
Nitrification ­ Oxidation Reaction, Aerobic. Changes Ammonium ions in to Nitrite ions and then
Nitrate ions.
Ammonification ­ Fungi and Bacteria feed on Ammonium containing compounds to release
Ammonia, which becomes Ammonium ions.
Nitrogen-Fixing bacteria…

Respiration:

4 Stages ­ Glycolysis, Link Reaction, Kreb's Cycle, Oxidative Phosphorylation. (That order)
Glycolysis is the only stage in anaerobic respiration. Ethanol is produced in plants and fungi,
Lactic Acid is produced in an animals.
Glycolysis:
o 6-Carbon 2 x 3-Carbon
o Produces NADH Stage 4
o Generates 2 net…

Mark-Release-Recapture Method:

Used to estimate abundance of a species.
Equation Total Size = (# caught in 1st sample x # caught in 2nd sample) / # marked in 2nd
sample.
Accuracy depends on time between readings, marking effecting the chance of survival and
change in population size.
