1. When a litter of kittens is born the mother allows them to work out among themselves
how they will acquire milk from her breast. In larger litters the smallest kitten is usually
left with less food or no food. This is an example of:
a. Intraspecies Competitive Exclusion
b. Interspecies Competitive Exclusion
c. Exploitation
d. Mutualism
2. O wls and Peregrine Falcons are both birds of prey that live in urban areas in North
America. These two species don’t usually directly compete with each other within their
ecosystem because…
a. The Owls hunt nocturnally and the Peregrine Falcons hunt diurnally allowing
them to primarily feed off of different prey in the area
b. They do directly compete and overtime it fluctuates which predator is more
dominant in their ecosystem
c. The Owls and Peregrine Falcons have different beak sizes making it impossible
for one to be able to eat smaller birds allowing for that resources to be exploited
by the other
d. Environmental changes in their area prevent either of them to become dominant
and hoard all of the resources
3. T wo species with identical niches are living together in a homogenous environment.
After sufficient time has passed we can conclude that…
a. One of the species will have left the area to find a new environment to live in
b. One of the species would be able to maintain a comparatively small population
due to the dominance of the other species
c. One of the species would have gone extinct due to interspecies competitive
exclusion
d. Global warming will have killed them both
4. A
body of water contains 6 different species of small fish that all have similar ecological
niches, and similar physical appearances. In spite of this they have all been able to
coexist for hundreds of years, this is likely due to…
a. The communication between species where they all agreed to stay out of each
other's way
b. Random chance allowing the species to all stay the same size
c. All of the species are being controlled by a parasite and
d. Predation allowing for any species that becomes most dominant to also be
consumed the most allowing for the balancing of the species
