Fluctuates

19

Multiple Choice

Question image

1

carrying capacity

2

population crash

3

lag phase

4

mutualism

20

Multiple Choice

Question image

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

1

Continues to grow

2

The population starts to die off to return to carrying capcity

3

The population will go extinct due to lack of resources

4

The population grows then finds a new carrying capacity

21

Multiple Choice

Question image

1
stay the same
2
decrease
3
increase
4
reach carrying capacity

22

Multiple Choice

2

The wolf population is decreasing

3

The wolf population increased

4

They ran out of food

23

Multiple Choice

Question image

24

Multiple Choice

Question image

a limiting measure

2

a limiting factor

3

carrying capacity

4

biodiversity

25

Multiple Choice

Question image

What happens if a population grows past its carrying capacity?

3

Depends on the ecosystem

4

Abiotic only

27

Multiple Choice

This may cause a population to increase

1

increase of food supply

2

removal of predators

3

removal of disease

4

all of these

28
