1.
Three bird species share a habitat. Bird A eats insects and plant seeds. Bird B drinks flower nectar. Bird C eats plant seeds.
A drought occurs in their habitat, and that season’s plants are wiped out entirely. What is the likely outcome for each type of bird?
Bird B survives; both birds A and C die.
Bird B survives; either bird A or bird C dies, and the other survives.
All of the birds die :(
Bird A survives; both birds B and C die.
2.
An increase in which of the following could increase the long-billed curlew population?
milkweed
grassland habitats
ocean habitats
pesticide use
Long-billed curlews eat many different kinds of insects, including grasshoppers, as a source of food. It has been shown that pesticide use kills many of these insects. How would you expect an increase in pesticide use to affect to the population of long-billed curlews in the same area?
It would stay the same.
It would increase.
It would decrease.
It would not be affected.
4.
How might bird populations on mountainsides respond to a warming climate?
The range shifts uphill over generations.
The range shifts downhill over generations.
There is not likely to be an effect based on a warming climate.
Their eggs will hatch later.
5.
What happened to North American coastal waters when the great white shark population decreased?
The clam population increased.
The human population increased.
The oyster population increased.
The ray population increased.
6.
Which organism is most responsible for the decrease in the great white shark population?
oysters
scallops
humans
rays
7.
Climate change is primarily driven by
photosynthesis.
fossil fuel burning.
mining.
deforestation.
8.
Hunting can be used to combat
invasive species
climate change
pollution
deforestation
9.
Fertilizer from agriculture flows into the ocean. What organism may directly benefit from this runoff?
fish
dolphins
algae
oysters
10.
Emperor penguins breed on shelves of sea ice in the winter. By spring, the chicks have developed waterproof plumage and are ready to swim in the cold ocean waters. What effect might a warming climate have on the penguins?
The chicks will grow into horse sized monsters and take over the world
The sea ice melts later in the season, and the penguins have to travel farther to find the perfect swimming hole
The sea ice melts before the chicks are ready to swim.
The sea ice freezes earlier in the winter which shifts the timelines in the metaverse
11.

Burmese pythons have no natural predators in the Everglades.
Burmese pythons were first introduced to Florida as pets.
