Name an autotroph
Any of the following answers are acceptable:corn, flowering plant, lavender, or mango
200
Which of these statements is true of parasitism
a.Parasitism is a relationship between two species where both organisms benefit from each other.
b.Parasitism is identical to predation since one organism kills another immediately since it is its food source.
c.The presence of a parasite does not affect the host.
d.The presence of a parasite may make an animal more vulnerable to predation.
d. The presence of a parasite may make an animal more vulnerable to predation.

Mercury (a pollutant) is passed through this food chain. Which organism is the first to absorb pollutants?
algae

Grasshoppers can either have green or yellow body colors. In the green grass, green grasshoppers can blend in with their environment and hide from predators.
Variation means the difference in traits.
The variation is the body color (some grasshoppers have green bodies and others have yellow bodies)

If the teritary trophic level contains 29 kCal of energy, how much energy do the primary consumers have?
2,900 kCal
300
Name one organism whose population would increase if the dragonfly population decreased?
The butterfly and fruit fly populations would increase since the dragonfly is the predator to those organisms
400
Which statement concerning the energy in the energy pyramid is correct?
a. Stored energy decreases as it is passed from consumer to consumer.
b. The producer contains the least amount of energy.
c. Consumers contain more energy than producers.
d. Decomposers are the source of energy for this pyramid.
a. Stored energy decreases as it is passed from consumer to consumer.

Grasshoppers can either have green or yellow body colors. In the green grass, green grasshoppers can blend in with their environment and hide from predators.
Which grasshopper has a better adaptation?
Adaptation is the trait that helps organisms to survive.
Green grasshoppers have a better adaptation because they can camouflage in the grass.
400
What do the arrows represent in this food web?
The flow of energy (Where energy goes to next)

A fox is carrying a dead squirrel as a hawk swoops down to grab it. They both pull on the squirrel but the flapping wings of the hawk against the face of the fox are strong enough to make the fox drop the squirrel. What type of relationship is seen?
predation

Barnacles live on the skin of the whale. The whale is unaware that the barnacles are there, but the barnacles get free transportation. What is the relationship between the whales and the barnacles?
commensalism

Set timer to 2 minutes!
Translate this DNA strand - TAC GCG TGC ATT
Answer: Met - Arg - Thr - Stop
1. You must first transcribe DNA into an mRNA, which is AUG CGC ACG UAA
2 Then translate mRNA into amino acids, which is Met - Arg - Thr - Stop

Grasshoppers can either have green or yellow body colors. In the green grass, green grasshoppers can blend in with their environment and hide from predators.
What would you expect to see in the grasshopper population after 5 generations if there is no change in the environment?
A. There will be more green grasshoppers since they have a better adaptation.
B. There will be more yellow grasshoppers because there are less predators.
C. There will be an equal number of yellow and green grasshoppers.
D. More yellow grasshoppers will be born because it is the better adaptation against the green grass.
A. There will be more green grasshoppers since they have a better adaptation.

phytoplankton->small fish-> large fish->birds.
Mercury is passed through this food chain. Which organisms would be better to eat a small fish or large fish? Explain your answer.
Small fish because they don't have as much mercury in their bodies since they are lower on the food chain.

kelp-> sea urchin->crab->sea duck-> fox
Sea otters move into the ocean bay and are predators for the sea urchins. This change will and cause the population
a. of kelp to increase because there is more available food for them to consume
b. of crabs to decrease because they have more competition for resources
c. of sea ducks to decrease because there is a lack of sea urchins for them to prey on
d. of arctic foxes to increase because there are more predators they will directly compete with
b. of crabs to decrease because they have more competition for resources
