Question

1. the finch population of a remote island is 1000 finches on average. choose the statement that best describes the climate during the five years shown in the graph below.

a year of drought followed by four years of average or above - average rain
a year of above - average rainfall followed by four years of drought
five years of drought
a year of average rain followed by four years of above - average rain

Explanation:

Finch populations are often affected by climate - rainfall in particular. Drought usually leads to a decrease in food sources for finches, reducing their population. In the graph, the finch population drops sharply in the first year and then recovers and fluctuates around or above the average population level in the next four years. This suggests a year of drought (causing the initial drop) followed by more favorable conditions (average or above - average rain) for the next four years.

Answer:

A. A year of drought followed by four years of average or above - average rain
