Question

when oil pollutes aquatic environments, it can harm wildlife in all of the following ways except
a. by coating organisms and their food sources
b. by killing the producers and disrupting food webs
c. by significantly dropping the water temperature
d. by interfering with oxygen absorption and production

Explanation:

Oil pollution coats organisms/food (A), kills producers disrupting food webs (B), and blocks oxygen exchange (D). Oil typically insulates water, slightly raising or stabilizing temperature, not significantly dropping it. Thus, C is the exception.

Answer:

C. by significantly dropping the water temperature
