Exam 3: Evolution,species Interactions,and Biological Communities

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?

A community with hundreds of different types of primary producers,a few herbivores,and only one carnivore,has

An organism's biotic potential is the maximum number of offspring

Which of the following does not contribute to limits on population growth?

________ is the development of a new species.

A tapeworm lives in the gut of an animal taking nutrients from the food the animal eats preventing the animal from receiving most of the nutrients.What type of symbiosis is this?

Which of the following are pioneer species?

The most common reason that introduced species cause trouble is because they are larger than native species.

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?

In the partnership of a lichen,the fungus provides ________ and the relationship is best described as ________.

Which of the following would be an example of high biotic potential?

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

A biological community's primary productivity is a measure of

________ habitat specialist found exclusively in one specific type of habitat.

Evolution occurs as a result of

Sled dogs have a thick coat of hair that helps them withstand the cold temperatures of the Arctic.Compare that adaption to a single,unrelated dog that grows a thicker coat in the fall in response to colder temperatures.The adaptation of the sled dog best describes adaptation at the ________ level while the dog exposed to seasonal colder temperatures has ________.

An especially effective strategy for reducing intraspecific competition is

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

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

Natural selection will ultimately make a species
