The orangutan has the longest childhood dependence on the mother of any animal in the
world. The babies nurse until they are about six years of age. Young females stay close to
their mother until they are into their teens, allowing them to observe mothering skills as
they watch their younger sibling being raised by the mother. Orangutan females only give
birth about once every 8 years – the longest time between births of any mammal on earth.
(This results in only 4 to 5 babies in her lifetime.) This is why orangutan populations are
very slow to recover from disturbance.
1. Based on the information above, orangutans are:
a. r-strategists
b. k-strategists
c. m-strategists
2. Based on the information above, the resilience of orangutans as a
species is:
a. relatively low
b. relatively high
c. on average with other species
3. Figure 1 below shows an area of land at different stages over time after being abandoned by a
farmer. The process of change from A to D is called:
a. resilience
b. equilibrium
c. primary succession
FIGURE 1
d. secondary succession

I.
The climax community is shown in picture A.
II. The climax community is shown in picture D.

in picture B

a. II only
b. I and III only
c. I and IV only
d. II and III only

6. The ability of a population to grow
under ideal conditions is known as:
a.
b.
c.
d.
e.
the critical number

7. Intraspecific
competition
tends to lead to:
a. the extinction of the species
b. density-dependent environmental resistance that regulates the
species’ population
c. natural selection and evolution
d. all of the above
e. b and c but not a
8. Interspecific
competition can
sometimes lead
to:
a. resource partitioning in which multiple species coexist in the same
habitat
b. a reduction in population of the less adapted species
c. extinction of the less adapted species
d. all of the above
e. b and c but not a
9. Purple
loosestrife is
a problem in
Morris
County, NJ
because:
a. they outcompete native species for resources
b. they are voracious predators that eat native plants and animals
c. they have low environmental resistance which has allowed their
population to grow exponentially
d. all of the above
e. a and c only
