Quizplus · Accepted Answer

According to the graph, when the habitable area is reduced from 10,000 km² to 1000 km², the number of species decreases from about 500 to about 150. This is a decrease of about 70%, which is equivalent to a loss of about 30% of the species (100% - 70% = 30%). Therefore, roughly 30% of the species would disappear. Answer choice C is the closest to this estimate.
