Exam 9: Population Ecology

Which statement is a basic lesson from nature? 

Which statement is a general description of a K-selected species? 

Logistic growth involves a rapid exponential population growth followed by a drastic decrease in population growth.

Which letter has the shape of an exponential growth curve that depicts an ever-growing population? 

POPULATION -Which letter in the diagram represents a population's capacity for growth?

In most cases,the effects of population increase,or of environmental resistance,are not felt instantly.

Which population dispersion pattern applies to an ecosystem with unevenly distributed resources? 

All r-selected species are specialists.

What is emigration? 

What is one reason for a population to overshoot its carrying capacity and crash? 

When a population reaches carrying capacity,the population's biotic potential gradually declines to a consistent value that is slightly greater than the original value.

What is carrying capacity? 

A population's growth rate will increase as the population reaches its carrying capacity.

Which type of species is more resistant to habitat fragmentation? 

Highly developed countries have such high rates of population growth because their birth rates are so high.

Which organism is an r-selected species? 

Which prediction is logical for a species in which uniform dispersion has been observed? 

Which statement is characteristic of inbreeding? 

A(n)____________________ can easily be wiped out because of its susceptibility to pathogens.

POPULATION -Which letter in the diagram corresponds to the size at which a population in a particular environment will stabilize and its supply of resources remains constant?
