Which of the following is NOT an abiotic factor?

Sunlight

Soil

A:

B:

Bacteria

Precipitation

C:

D:

slide3

$ 100

C.

BACTERIA…Abiotic factors are non-living, and bacteria is MOST DEFINITELY ALIVE.

slide4

Which of the following would be the habitat of a

Bluejay?

An oak tree

A snake

A:

B:

Sunflower seeds

None of the above

C:

D:

slide5

$ 200

A.

An Oak Tree…Habitat is where an organism lives

slide6

Which of the following is a predator of

the grasshopper?

Marsh grass grasshopper frog snake

Carrots

A frog

A:

B:

A Hawk

Marsh grass

C:

D:

slide7

$ 300

B.

A frog. A predator is an organism that captures and feeds on another organism… in this case-the grasshopper

slide8

Click here to see an image of a lichen. What type

of organism is a lichen in terms of ecological

succession?

A Fungus

Start-up organism

A:

B:

Dirt-breaker

Pioneer Species

C:

D:

slide9

$ 500

D.

A pioneer species is the first organism to inhabit an area. A lichen is a common pioneer species.

slide10

Which of the following is NOT a symbiotic

relationship that can be found in an ecosystem?

Mutualism

Predation

A:

B:

Parasitism

Commensalism

C:

D:

slide11

$ 1,000

B.

Predation…while predation is an interaction within an ecosystem, it is NOT a symbiotic relationship

slide12

A symbiotic relationship in which one organism

benefits while the other is harmed is known

as _________________.

commensalism

competition

A:

B:

parasitism

mutualism

C:

D:

slide13

$ 2,000

C.

Parasitism…In the example provided, the tick feeds on blood from its host. This benefits the tick, but harms the host.

slide14

Which of the following could be a cause of

secondary succession?

Logging

Planting trees

A:

B:

A new species of birds being discovered.

A thunderstorm

C:

D:

slide15

$ 4,000

A.

Logging… which is a form of deforestation destroys and ecosystem and requires it to be restored.

slide16

View the images of a receding glacier by clicking

HERE. Place them in the correct order that

Primary succession would occur.

3,1,2

1,2,3

A:

B:

Primary succession cannot be caused by a receding glacier.

2,1,3

C:

D:

slide17

$ 8,000

C.

2,1,3… succession shows a GRADUAL change in a community over time as seen in the example

slide18

A necessity of life such as water, sunlight, food,

and space are examples of ___________.

resources

A:

B:

Biological compounds

Life’s factors

C:

D:

Details of an ecosystem.

slide19

$ 16,000

B.

Resources.

slide20

A biological relationship in which two organisms

live closely together is known as ____________.

Succession

Competition.

A:

B:

Symbiosis

Love

C:

D:

slide21

$ 32,000

D.

Symbiosis...there are 3 types (commensalism, mutualism, and parasitism)

slide22

Which of the following would be a reason for

competition among organisms?

mates

food

A:

B:

Space/habitat

All of the above

C:

D:

slide23

$ 64,000

D.

All of the above… Competition occurs when organisms attempt to use the same resource at the same time.

slide24

A clown fish hides inside of a sea anemone for

protection. Predators cannot get to the clown fish

without being injured from the “sting” of a sea anemone.

The clown fish, however, cannot be injured. The sea

anemone is neither helped nor harmed. What type of

symbiotic relationship is this?

CLICK HERE TO SEE IT

commensalism

competition

A:

B:

predation

mutualism

C:

D:

slide25

$ 125,000

A.

Commensalism…a symbiotic relationship in which one organism benefits and the other is neither helped nor harmed.

slide26

The competitive exclusion principle states that two

organisms of the same species CANNOT occupy

the same niche at the same time. What is the

ultimate outcome of this situation?

A niche has nothing to do

with competition

One of the two species will not survive

A:

B:

One of the two species will move to another location

Both species will learn to live along side each other

C:

D:

slide27

$ 250,000

B

A niche is an organisms role in the environment. One of the two will NOT survive.

slide28

Why does secondary succession occur much

more quickly than primary succession?

The pioneer species are already present

It doesn’t, primary succession occurs more quickly.

A:

B:

Because soil is already present and it does not take as long for plants to establish themselves.

There are animals present to spread the seeds for regrowth.

C:

D:

slide29

$ 500,000

C.

It takes a very long time for pioneer species to breakdown rocks and turn into soil… therefore secondary succession occurs much faster because soil is already present.

slide30

Look at the circled portion of food chain below.

Which of the following are ALL niches the

grasshopper?

Marsh grass grasshopper frog snake

Consumer, herbivore, prey

Consumer, carnivore, predator

A:

B:

Producer, herbivore, predator.

Consumer, carnivore, prey

C:

D:

slide31

$ 1,000,000

B.

A niche is the role of an organism within an ecosystem. A niche can be related to it feeding relationships.
