Question

though black rhinos once roamed europe, asia, and africa in large numbers, poaching and habitat loss over the past century led to a quick decline in population. fortunately, conservation efforts have saved these animals from extinction, and their numbers are slowly increasing. which graph could show the population of rhinos over the last century? four graphs with population of rhinos (y - axis) and time (decades) (x - axis) are shown, each with different curves: first graph has a peak then decline, second has decline then increase then stabilize, third has high then low then slight increase, fourth has decline then low then increase

Explanation:

Step1: Analyze the population trend

The problem states that black rhinos had a large population, then a quick decline (due to poaching and habitat loss), and then a slow increase (due to conservation efforts). So the graph should show an initial high population, a decrease, and then an increase.

Step2: Evaluate each graph

• Top - left: Increases, then decreases, no recovery. Doesn't match.
• Top - right: Decreases first, then increases, then stabilizes. Doesn't match the initial large population.
• Bottom - left: High initial, then decreases to low, then increases. Matches the trend (large population, decline, then increase).
• Bottom - right: Decreases, then increases, but the initial trend isn't a high population first. Doesn't match.

Answer:

The graph at the Bottom - Left (the third graph, bottom - left position)
