2 5 points An example of symbiosis is a. a hawk hunting a mouse b. a school of fish swimming together c. a butterfly sipping nectar from a flower d. wolves fighting over territory
3 c. A butterfly sipping nectar from a flower.
4 10 points A remora hitching a ride on a shark is an example of _________.
6 15 points A tick sucking a dog’s blood is an example of __________.
8 20 points Aphids make a sweet substance that ants eat. The ants protect the aphids. This is an example of ____________.
10 25 points Explain how the faces represent certain symbiotic relationships.
11 Two smiles = Mutualism One smile, One no smile = Commensalism One smile, One frown = Parasitism
12 5 points The gradual change from a barren environment to a stable ecosystem is called _________.
13 Primary Succession
14 10 points After a forest fire, grasses and small shrubs begin to grow. Eventually, trees grow back. This is an example of __________.
15 Secondary Succession
16 15 points A gradual series of changes in an area’s communities is called_______.
18 20 points Moss growing in a bare rock environment is a _________.
19 Pioneer Species
20 25 points What can trigger Secondary Succession?
21 Floods or fires
22 5 points Male deer fighting over territory is an example of __________.
24 10 points Lions hunting together is an example of ______________.
26 15 points In 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 ________.
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 points It’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 points Grazing 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 points An 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 points Explain 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.
