Question 4

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.

Accepted Answer

A)   zone of intolerance
B)   tolerance limit range
C)   zone of physiological stress
D)   optimal range
E)   range of tolerance

Question 5

Accepted Answer

A) True 
 B)False

Question 6

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

Accepted Answer

A)   species in the population.
B)   species at each trophic level.
C)   genetic variations within a species.
D)   primary producers available.
E)   primary producers relative to the number of consumers.

Question 7

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 _____________.

Accepted Answer

A)   regional; natural selection at the individual level
B)   individual; physiological modifications at the population level
C)   population; physiological modifications at the individual level
D)   species; natural selection at the population level

B)   rapid reproduction.
C)   eating prey before they are "ready" (ripe)  for other species.
D)   resource partitioning.
E)   None of these since the examples given are for reducing interspecific competition.
