Black skimmers are water birds that live along coastal beaches, bays, estuaries, and marshes. They fly just above the
surface of the water using their lower jaw to catch small fish, shrimp, and other small crustaceans.
These birds nest in simple, unlined depressions in the sand. Scientists have observed a decline in the number of
nests. Some causes of this decline include a lack of suitable nesting sites, beach erosion, and human disturbances.
When people approach their nests, the birds become aggressive and chase away intruders. Other animals, like crows,
will take advantage of the unprotected nests and feed on the eggs.
A) A continued decrease in black skimmer
populations will most likely lead to:

B)A decrease in scavenger populations

C)An increase in producer populations

D)A decrease in decomposer populations
An increase in prey animal populations
