Exam 3: Evolution, Species Interactions, and Biological Communities

A titmouse and a chickadee are living in the same territory and are using some of the same resources. The best way to classify this interaction is as

The introduction of a predator onto an island originally free from predators is likely to cause the extinction of a native species.

An especially effective strategy for reducing intraspecific competition is

Use the following example for the question. A species of fish can withstand a narrow range of temperature. Above 100°F there are no individuals present. In the range from 97°F-100°F and 90°F-94°F there are a few individuals present. Below 90°F there are no individuals present. Between 95°F-96°F there are many individuals. -What would you label the range of temperature from 95°F to 96°F for this particular species?

A climax community is one that

Use the following example for the question. A species of fish can withstand a narrow range of temperature. Above 100°F there are no individuals present. In the range from 97°F-100°F and 90°F-94°F there are a few individuals present. Below 90°F there are no individuals present. Between 95°F-96°F there are many individuals. -What is the difference in the adaptation of a sled dog's (such as a Husky) thick coat of hair to help it withstand the cold temperatures of Arctic winters and a dog that adapts to cold temperatures in the fall by growing a thickened coat? The adaptation of the sled dog best describes adaptation at the ____________ level while the dog exposed to seasonal colder temperatures has _____________.

Complexity in an ecological community has to do with the number of

In the real world, many factors determine the numbers of organisms in any one population. Yet, a SUPERFLY with unlimited food and no mortality would show what type of growth?

What term describes species which arise in non-overlapping geographic regions?

A dieback, or population crash, often occurs after a species ________ its environmental carrying capacity.
