usually small
mature rapidly
reproduce rapidly with lots of offspring
short life span

Question 2

k-strategists qualities

Answer 2

long life expectancy
mature slowly
few offspring but extensive parental care
population usually close to carrying capacity

Question 3

competitive exclusion principle

Answer 3

two species cannot occupy the same niche at the same time for very long

Question 4

character displacement

Answer 4

evolutionary divergence of characteristics that overlap with species that share the same niche

Question 5

resource partitioning

Answer 5

division of resources by coexisting species to avoid competition

Question 6

carrying capacity

J-curve

Answer 7

r selected species growth curve - density independent

Question 8

S-curve

Answer 8
