An oil spill that prevents marine birds from flying and hunting will lead to
a scarcity of predators of marine birds.
an overabundance of certain fish and crab species.
a scarcity of certain fish and crab species.
an overabundance of marine birds.
An ocean area has a high number of plants and animals. What happens if otters are hunted a lot?
the biodiversity remains the same, as does the # of otters
the biodiversity increased and there were more otters
there came to be no biodiversity and no sea otters
the biodiversity decreases and there are fewer otters
If waste is not disposed of the right way it can end up -
causing acid rain in the atmosphere
causing landfills to overflow.
contaminating the soil & causing runoff to flow into water
causing serious air pollution.
Pollution causes harmful algae to bloom. How does this affect organisms in marine waters?
prevents them from receiving enough sunlight
benefits the organisms by providing them with many nutrients
prevents organisms from becoming parasites of the algae
benefits the organisms by increasing water temperature
Which would most likely cause a change in the genetic traits of an isolated groups of snakes?
Introduce a predator that preys on the brightest colored snakes into the ecosystem.
An unusually dry summer in the snakes ecosystem.
Exposing one snake to radiation causing a mutation that does not get passed on to the next generation.
A flood that causes the grasses in the ecosystem to grow.
The snowshoe hare's fur is brown in the summer and white in the winter.
If global climate change leads to the elimination of snow in the habitat of the snowshoe hare, which adaptation is most likely to occur over many generations?
Hares with white fur will be easier to see on the ground in the summer. Over time this could lead to Snowshoe hares that have white fur throughout the year.
Snowshoe hares with brown fur will be easier to see on the ground in the winter. Over time this could lead to Snowshoe hares that have brown fur throughout the year.
Hares with brown fur in areas without winter snow will be easier for predators to find. Over time this could lead to Snowshoe hares that have white fur throughout the year.
Hares with white fur in areas without winter snow will be easier for predators to find. Over time this could lead to Snowshoe hares that have brown fur throughout the year.
Estuaries are waterways between pieces of land. The amount of salt water and freshwater changes with the tides. A variety of plant species live in this ecosystem and provide a habitat for other organisms.
What adaptation would best help a plant species successfully live in an estuary ?
Storing excess gases.
Filtering excess salt.
Absorbing large amounts of water.
Producing large amounts of food.
Which of the following water conditions would cause the most competition for resources among all three species of fish?
Mild temperatures, some suspended particles, flows at a medium speed
Very cold, very clear, and very fast
Mild temperatures, some suspended particles, flows very fast
Very warm, very clear, and very slow
The graph shows information about eating habits of a population of deer. A rancher is concerned about competition between the ranch animals and the deer.
Based on the graph, which ranch animals compete for the most food with these deer?
Chickens that eat seeds and fruit
Sheep that eat grass and feed
Goats that eat weeds and shrubs
Horses that eat fruit, seeds, and feed
A scientist studies marine species that live on the ocean floor. In some areas Sea Pens are found alone. In other areas areas Brain Coral is found alone. In still other areas both species are found together. The diagram shows them in their habitats.
If Brain Coral were removed from the areas it shares with Sea Pens, Sea Pens would most likely inhabit —
The Continental Shelf
The Intertidal Zone
The Photic Zone
the Aphotic Zone
