20
Q

Each species has a specific…

A

role

21
Q

(r) selected species characteristics

A
  • growth w/o much environmental resistance
  • small
  • lots of offspring
  • no parental care
  • mature quickly
  • opportunistic
22
Q

(K) selected species characteristics

A
  • large
  • parental care
  • few offspring
  • mature slowly (years opposed to days/weeks)
  • Stable
23
Q

Population Density

A

thing/area

dense=disease spreads quicker

24
Q

Clumped dispersion

A
  • most common
  • mostly found in animal
  • they are where resources are
25
Q

Uniform and Random dispersion

A

mostly found in plants

26

Mutualism (+,+)

A

both benifit

27
Q

Comensalism (+, 0)

A

one benefits, the other is not bothered

28
Q

Parasitism (+, 1/2 -)

A

one benefits, one is harmed but not killed

29
Q

Preditation (+,-)

A

one benefits, one is killed

30
Q

Competition (-,-)

A

both are not benefited

31
Q

Resource partitioning

A

evolving to gain resources around other species

32
Q

Co evolution

A

two species evolving in spite of eachother

33
Q

primary succession

A

starts with nothing

34
Q

secondary succession

A

mostly gone (like a forest fire destroying most of a forest)
