A.   Goats eat grass; the goats are milked and eaten by humans

B.   Seeds and grasses are eaten by various insects and small herbivores, the insects are eaten by a meadowlark, the small herbivores are eaten by a hawk, the meadowlark and the hawk eggs are eaten by snakes, and the snakes are eaten by owls.

C.   Seeds are eaten by a tufted titmouse, the titmouse is eaten by a hawk, the hawk eggs are eaten by snakes, and the snakes are eaten by owls.

D.   Seeds are eaten by sparrow, the sparrow is eaten by a hawk, and the hawk's eggs are eaten by a snake.

A.   drive their prey to extinction

B.   quickly alter the behavior of their prey

C.   cause the abundance of their prey to rise

B.   it has occurred relatively slowly

C.   CO2 reacts so quickly with other compounds that it should not be occurring

D.   there is no known mechanism for its occurrence

A.   Prey species, such as mussels, would decline, but most species within the community would be unaffected.

B.   The communities would be statistically indistinguishable from one another.

C.   Other predators will simply replace P.ochraceus and take advantage of prey that P.ochraceus consumed
