Multiple Choice

Multiple Choice

What is the carrying capacity of the graph?

• less than 500

• more than 500

• around 500

Multiple Choice

In the graph to the right, what is the population of deer at the carrying capacity of the environment?

• 3

• 7

• 40

• 70

Multiple Choice

When a population grows past the ecosystem's carrying capacity, what happens to the population?

• It continues to grow higher and higher.

• The population will go extinct due to lack of resources.

• The population starts to die off and returns to the carrying capacity.

Multiple Choice

Carrying capacity is...

• The maximum number of individuals that can fit into an area

• The greatest # of individuals an area can support over time.

• Ability of an area to accommodate a growing population

• The maximum number of species that can co-exist in an area

Multiple Choice

When water used to cool machinery is returned to a river, it raises the river water temperature. This causes a sharp decline in small invertebrate populations. Based on the food web, a likely consequence of this change would be:

• an increase in the number of clams

• an increase in the number of water plants

• an increase in the number of crayfish

• an increase in the number of crabs

Multiple Choice

Food, water, space, sunlight, air, soil are resources that are often __________.

• limiting factors

• carrying capacity

• population density

• population decline

Multiple Choice

If a disease destroying barley plants in a field swept through an ecosystem, what would happen to the barley eating bird population in the the field ?

• The bird population would stay the same

• The bird population would decrease

• The bird population would increase

Multiple Choice

Which of the following statements is true?

• An increase in water will decrease the carrying capacity.

• A fishes population cannot exceed the carrying capacity

• A population can't change once it's at carrying capacity.

• A decrease in food availability lowers carrying capacity.

Multiple Choice

What would happen if the population of hawks suddenly increased? How would it affect the other organisms in the ecosystem?

• The snakes would decrease due to more hawks eating them

• All of the population of organisms would increase

• The hawks predators would decrease

• The biotic factors in the ecosystem would increase

Multiple Choice

When resources are NOT available a population will _____________ in size.
