taxonomy
the process of classifying living things
3 domains
archeae
mostly extinct
prokaryotes
eukaryotes
eukarya kingdoms
population
of same species in an area at a given time
community
lots of populations
ecosystem
lots of communities
symbiotic relationships
mutalism
positive for both
parasitism
positive for one, negative for one
competition
negative for both
predation
predator populations closely follow changes in prey populations
biotic potential
of potential offspring 1 individual could have
theory of overproduction
not all offspring survive to adulthood
environmental resistance
density dependant
density increase –> loss of population
density independant factor
will limit a population but are not influenced by the size of the population
ex. flood
population measurements
quadrats
quadrats
percent error
(experimental - theoretical) / theoretical x 100 = %
transects
mark - recapture
