When a population grows past the ecosystem's carrying capacity, what happens to the population?
It continues to grow higher and higher.
The population starts to die off and returns to the carrying capacity.
The population will go extinct due to lack of resources.
The graph to the right shows the interaction of the wolf and moose populations on Isle Pekie. If the moose population continues to increase, the wolves' food supply will increase. What will most likely happen to the wolf population as a result?

The salamanders will move across land to another river.
The salamanders will quickly adapt to living in the muddy water.

A sample of bacteria was added to a culture dish containing a limited food supply. (Culture dishes are designed to help bacteria grow.) The dish was kept in an incubator for two weeks, where temperature that bacteria prefer to live in was kept constant.

The bacteria ate all of the available food.
The bacteria could not grow at all in the provided temperatures.
The bacteria could not grow at all with the provided food type.
