100%
10%
1%
15
According to the graph shown, what effect did the brown tree snake have on the birds in Guam?
The snakes formed a mutualistic relationship with the birds.
The snakes had no effect on the bird populations.
The snakes caused an increase in the number of bird pops.
The snakes caused a decline in the number of bird pops.
16
Pioneer Species -->
The lichen does not require sunlight to survive.
The lichen is a decomposer that digests rocks & forms soil.
The mutualistic relationships in it allows it to survive.
The lichen is fast growing & provides food for other species
17
Identify 2 specific pops that most likely increased in # if the mountain lion pop decreases.
Rabbit and snake
Mouse and deer
Rabbit and deer
Mouse and hawk
18
Using the diagram, why will the herbs and shrubs most likely replace the lichens and mosses?
lichens/mosses will change the env for herbs/shrubs to grow
An inc. in C02 in the soil will allow taller plants to grow
Dense shrubs are the climax community for this environment.
Increased cultivation by humans will make more fertile soil
19
In what manner do bacteria cause disease?
They generate heat that kills nearby cells.
They cause cracks in the skin, which allows dirt to enter.
They damage tissues and release toxins.
They integrate themselves into the host cell’s DNA.
20
How would a disease that infects and kills jerboa most directly affect this food web ?
Raptor and coyote populations would likely increase.
The biomass of rattlesnakes and lizards would increase.
Leafcutter ant populations would compete more for food.
Rattlesnake, badger, and lizard pops would likely decrease.
21
How does the burning of fossil fuels affect the cycle shown?
It removes carbon from the atmosphere.
It releases carbon into the atmosphere.
It both releases and removes carbon from the atmosphere.
It releases ozone into the atmosphere.
22
Which organism in the food web to the right would be considered both a 1 and 2 consumer?
Grasshopper
Rabbit
Mouse
Spider
23
Which factors could be affecting the long-term survival of the axolote species?
The canals where the axolote live are being polluted.
Cod & tilapia are eating the limited food source of axolote.
Carp & others eat axolate eggs & the plants its eggs are on
All of these
24
Which describes the most likely effect of removing plants from the area by chem herbicides?
The infiltration of water into the ground would be halted.
The rate of erosion of rocks on the ground would be slowed.
The flow of necessary nutrients would be disrupted.
Ability of plants to complete photosynthesis would be INC
25
How would an exotic/nonnative species likely interrupt the balance freshwater pond ecosystem?
It would attract more animals than can be sustained.
It would cause an overproduction of oxygen and kill fish
