HSA Questions
1) 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. Which of these terms
best describes the relationship between the crows and the black skimmers?
A. mutualism
B. commensalism
C. parasite–host
D. predator–prey
2) A protozoan lives inside a rat and takes its nourishment from the rat’s body. Because the protozoan damages
the rat’s brain, the rat loses its fear of cats. A cat attacks an infected rat; the protozoan enters the cat’s body and
completes its life cycle.Which of these describes the relationship between the protozoan and the rat?
A) commensalism
B) parasite–host
C) mutualism
D)predator–prey
