Question

Figure 54.7 -Based on the species- area plot in the figure above, if habitable area on an island were reduced from 10,000 km² to 1,000 km², roughly what percentage of the species would disappear?

Quizplus · Accepted Answer

The species-area plot shows an exponential curve, which means that as the area decreases, the number of species also decreases at an increasingly rapid rate. Using the curve to estimate the percentage of species lost, a reduction in habitat from 10,000 km² to 1,000 km² would result in a loss of approximately 30% of the original species. Therefore, the best choice is C.
