Question

the population of fish in a pond in relation to the number of years since stocking is depicted on a graph. for the first few years after the pond is stocked, the population grows slowly. it increases more quickly as the fish reproduce, then it levels off. a pollutant kills off almost all of the fish 20 years after stocking. the population begins to grow again when the remaining fish reproduce. which graph depicts the situation described above? a. graph with population on y - axis and time (years) on x - axis showing a curve that first rises slowly, then more quickly, levels off, drops sharply and then rises slightly again b. graph with population on y - axis and time (years) on x - axis showing a curve that rises, levels off and then drops sharply to zero and then rises slightly again

Explanation:

The population starts slow, then grows faster, levels - off, drops sharply due to pollutant, and then grows again. Graph b shows a slow start, growth, a sharp drop, and then regrowth which matches the description. Graph a does not show the sharp drop and regrowth properly as it has a smooth decline.

Answer:

b.
