Competition 23
10 points Lions hunting together is an example of _______. 24
Cooperation 25
15 points In what ways do organisms of the same or different species compete? 26

20 points Male peacocks displaying their 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. 51
