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

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
