9.1 Population Flashcards
Population
organisms in the same place at the same time who can reproduce together
Population Density
of individuals/area
Population Distribution
Pattern in which organisms of a population are spread throughout a range
Random vs. Uniform vs. Clumped
Random- organisms are randomly spread out, inhibits the growth of nearby populations
-Clumped- organisms are in groups, helps find a favorable environment
Uniform- organisms are very evenly spread out, favored conditions are localized and easily accessible
Random Sampling
of organisms in sample/area of sample=total # of organisms/total area
Mark and recapture
total marked/# of total organisms= total recaptured with marks/ # of organisms recaptured
