The red imported fire ant is an invasive species that has affected many native species in North America. Scientists wanted to see the effect of the fire ants on the survival of a certain kind of native bird. They treated nests of the bird with a chemical that kills the ants. They treated a different percentage of bird nests in different areas. In some areas, only 25% of the bird nests were treated with the chemical. In other areas, 100% of the bird nests were treated with the chemical.

The graph below shows the percent of birds surviving compared to the percentage of bird nests treated with the ant-killing chemical.




What conclusion about the effects of fire ants on the birds is best supported by the graph?
A.
The birds are more likely to survive when there are many fire ants, so the ants are likely outcompeting the birds for resources.
B.
The birds are more likely to survive when there are many fire ants, so the ants are likely providing resources for the birds.
C.
The birds are less likely to survive when there are many fire ants, so the ants are likely taking over the niche of the birds.
D.
The birds are less likely to survive when there are many fire ants, so the ants are likely predators of the birds.

Some scientists studying aquatic plants notice that flooding often leads to a decrease in the rate of photosynthesis among aquatic plants. Flooding causes more sediment to be suspended in thewater. The increased sediment concentration decreases the amount of light that reaches the plants. Why does a decreased rate of photosynthesis lead to a decrease in a plant population?

A. Less water is available for adsorption

B. Less tissue for plant growth

C. Less soil is available for leaf development

D. Less energy is available for reproduction​
