a)
overpopulation
b)
extinction
c)
migration
d)
adaptation
11.

increase in amount of grass
b)
decrease in amount of grass
c)
overpopulation in squirrel population
d)
increase in rabbit population
12.

c)
could continue reproducing at an increasing rate 
d)
is about to increase dramatically in population 
13.
