Let's go through each question one by one:
-
Which of the following is expected to happen to a species' population when resources are stable over a long period of time and the species have reached carrying capacity?
- Correct Response: The population will stay the same.
-
Which factor may increase a rabbit population?
- Correct Response: decrease in predators. (Fewer predators would likely lead to an increase in rabbit population.)
-
A group of mountain gorillas has 10 members. How big is the group after 4 females emigrate, 2 females immigrate, 2 gorillas are born, and a male dies?
- Calculation: 10 - 4 + 2 + 2 - 1 = 9.
- Correct Response: 9.
-
Predator/prey interactions regulate the populations of both groups. Which chain of events follows from an increase in predators?
- Correct Response: decrease in prey → increase in predators → decrease in prey. (As prey decreases, predators may temporarily increase due to better food availability, but ultimately, the prey population will decrease further.)
-
In the image, a coyote has caught and killed a badger. The coyote’s aim is to eat the badger to obtain the energy it needs to survive. What type of relationship is described?
- Correct Response: predator-prey. (The coyote is the predator, and the badger is the prey.)
