20

25 points What can trigger Secondary

Succession?

21

Floods or fires

22

5 points Male deer fighting over territory is

an example of __________.

23

Competition

24

10 points Lions hunting together is an example

of ______________.

25

Cooperation

26

15 pointsIn what ways do organisms of the

same or different species compete?

27

For food, water, space and other resources

28

20 points Male peacocks displaying their feathers to attract a mate is an

example of ________.

29

Competition

30

25 points What do plants compete for?

31

Sunlight, space, water and nutrients

32

5 points What does a limiting factor do?

33

Limits the growth of a population

34

10 points What can cause a population to

grow?

35

Fewer predators, more food

36

15 pointsIt’s something that helps determine

the growth of a population in an ecosystem.

37

Limiting Factor

38

20 points Nutrients are added to a waterway,

causing the algae population to grow rapidly. Nutrients are a ________ for

the algae.

39

Limiting Factor

40

25 points An unsually cold winter causes the

squirrel population to decrease. This example of a limiting factor is the

________________.

41

Temperature decrease

42

5 points The _______________ of an environment is the maximum population that it can support.

43

Carrying Capacity

44

10 pointsGrazing in a herd benefits a deer population because it gives them

____________.

45

Protection from predators

46

15 points

Can a organism be both prey and predator? How?

47

Yes, for example a bird that eats a caterpillar is in turn eaten by a

hawk.

48

20 pointsAn ecosystem’s carrying capacity is different for each population. Why?

49

Lower level consumers are in greater numbers because they consume primary consumers.

50

25 pointsExplain how symbiotic relationships

are similar to and different from prey-predator interactions.

51

Prey-predator relationship, one species benefits and the other is

harmed. Similar to parasitism but the parasite relies on the host for survival so they do not want to

kill their host.
