1.
The snail attach themselves to the kelp and seaweed in the ecosystem so the current does not take them all over the place. They are not strong enough swimmers to control their movement. The snails and seaweed are in what type of relationship do they have?
a)
predator/prey
b)
symbiotic mutualism
c)
symbiotic commensalism
d)
competition
2.
If the population of the snail were to decrease what immediate effect would they have on the seaweed since they are in a commensalism relationship?
a)
Increase
b)
Decrease
c)
Unaffected
3.
Why would the snail have no immediate effect on the population of the seaweed?
a)
The snail needs the seaweed to hold onto so they are not eaten, but the seaweed does not need the snail
b)
The snail does not eat the seaweed
c)
The snail and seaweed are in competition
4.
If the population of the seaweed were to decrease what effect would this have on the snail since they are in a commensalism relationship?
a)
Increase
b)
Decrease
c)
Unaffected
5.
Why would population of the snail decrease?
a)
Because the seaweed provides a place for the snail to attach so they don't get eaten as easily
b)
The snail eats the seaweed so they now have less food
c)
They are in a mutualistic relationship so when the seaweed decreases so does the snail
d)
They are in competition so when the seaweed decreases so does the snail
6.
What is the name of Sylvester the Cat's son?
a)
Jack
b)
Cecil
c)
Chuck
d)

7.
The seaweed and limpet have a relationship. The limpets clean the seaweed so that they can get carbon dioxide & light easier. The seaweed provides some of it's photosynthesis energy to the limpet (the limpet does not actually eat the seaweed. This is a...
a)
Competition
b)
Similar to predator/prey
c)
Symbiosis mutualism
d)
Symbiosis commensalism
8.
The limpet population increases. What effect would it have on the seaweed since they are in a mutualistic relationship?
a)
Increases
b)
Decreases
c)
Unaffected
9.
Why would the seaweed population increase?
a)
The seaweed is cleaned by the limpet. More limpet means more cleaning & more photosynthesis
b)
The seaweed gets energy directly from the limpet. The limpet goes through photosynthesis and gives the seaweed energy. So more limpets means more energy from the limpet
c)
The seaweed preys upon the limpet. Since their are more limpet they now have more energy
10.
The seaweed population decreases. What effect would it have on the limpet since they are in a mutualistic relationship?
a)
increases
b)
decreases
c)
unaffected
11.
Why would the limpet population decrease if the seaweed population were to decrease?
a)
The seaweed gives some of the energy it makes from photosynthesis to the limpet.
b)
The limpet feeds upon the limpet
c)
The limpet is in competition with the seaweed
d)
The limpet is the prey of the seaweed
12.

b)
Symbiosis: Parasitism
c)
Symbiosis: Mutualism
d)

If the population of the barnacle were to decrease what would happen to the crab in a parasitic relationship?
a)
Increase
b)
Decrease
c)
Unaffected
15.
Why would the crab population increase if the barnacle population were to decrease?
a)
The barnacle is a parasite to the crab.
b)
The barnacle is the predator to the crab.
c)
The barnacle is in competition with crab
16.
If the population of the crab were to increase then the population of the barnacle would do what in a parasitic relationship
a)
Increase
b)
Decrease
c)
Unaffected
17.
Why would the barnacle population increase if the crab population increased?
a)
The barnacle is a parasite that attacks the crab.
b)
The barnacle is a predator of the crab
c)
The barnacle is in competition with the crab
d)
They are in a mutually beneficial relationship (symbiotic mutualism)
