13
Q

environmental resistance

A
  • biotic or abiotic
  • generation is limited by factors in their environments
14
Q

density dependant

A

density increase –> loss of population

15

A

will limit a population but are not influenced by the size of the population

16

population measurements

A

quadrats

17
