of ______________.
24
Cooperation
25
15 points
In what ways do organisms of the
same or different species compete?
26
For food, water, space and other
resources
27
20 points

feathers to attract a mate is an
example of ________.
28
Competition
29
25 points
What do plants compete for?
30
Sunlight, space, water and
nutrients
31
5 points
What does a limiting factor do?
32
Limits the growth of a population
33
10 points
What can cause a population to
grow?
34
Fewer predators, more food
35
15 points
It’s something that helps determine
the growth of a population in an
ecosystem.
36
Limiting Factor
37
20 points
Nutrients are added to a waterway,
causing the algae population to grow
rapidly. Nutrients are a ________ for
the algae.
38
Limiting Factor
39
25 points
An unsually cold winter causes the
squirrel population to decrease. This
example of a limiting factor is the
________________.
40
Temperature decrease
41
5 points
The _______________ of an
environment is the maximum
population that it can support.
42
Carrying Capacity
43
10 points
Grazing in a herd benefits a deer
population because it gives them
____________.
44
Protection from predators
45
15 points
Can a organism be both prey and
predator? How?
46
Yes, for example a bird that eats
a caterpillar is in turn eaten by a
hawk.
47
20 points
An ecosystem’s carrying capacity is
different for each population. Why?
48
Lower level consumers are in
greater numbers because they
consume primary consumers.
49
25 points
Explain how symbiotic relationships
are similar to and different from
prey-predator interactions.
50
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.
