Ecology Unit Exam Review

A population of fish went from 30 to 30,000 in 20 years. During year 21, their food source was depleted (gone) due to a pollutant and their population dropped to 15!

Are the fish above or below carrying capacity during year 21?

• Above

• Below

The amount of different living things in a particular area is known as...

• biofeedback

• foodwebs

• biodiversity

• science

A population of fish went from 30 to 30,000 in 20 years. During year 21, their food source was deplete (gone but NOT COMPLETELY) due to a pollutant and their population dropped to 15!

What do you think caused the change in carrying capacity to occur?

• the resources available increased

• the resrouces available decreased

• the resources available disappeared

• nothing happened to the resources

Rabies enters the forest ecosystem and kills off all the primary consumers in the area. How will this impact the ecosystem?

• Plant eating organisms will increase

• Carnivores and omnivores would starve to death

• The ecosystem would grow over with plants

• Nothing would happen

The southwestern pan handle of Pennsylvania the white tailed deer has a shortage of white tailed deer. What can be done to increase the deer population and fix this problem?

• Grow deer in a lab

• Shorten the hunting season

• nothing needs to happen

• limit the number of deer that can be hunted

The southwestern pan handle of Pennsylvania the white tailed deer has a shortage of white tailed deer. The DNR enforces a 2 deer policy for hunting season. How would you know that what the DNR put in place works?

• Determine the deer population before the solution is put in place and after the solution has been put in place

• Have hunters fill out a survey

• Measure the size and weight of each deer that is killed

• Nothing and hope for the best :)

In parts of Africa, Cheetahs and Zebras are in the same biological community. Zebras are food for the Lions. How would an increase in the cheetahs birth rate most likely impact the zebras?

• The zebras birth rate would increase

• The Zebras birth rate would not change

• The Zebras death rate would increase

In parts of Africa, Cheetas and Zebras are in the same biological community. Zebras are food for the Lions. How would a decrease in the Cheetas birth rate affect the Zebras?

• The Zebra birth rate would increase

• The Zebra birth rate would decrease

• Nothing would happen
