Answer:
Third graph.
Explanation:
From the given characteristics we can deduct which graph is correct.
First, the population of primates is expected to decline in the long run. This means that the graph must decrease at the end period, that let us only two options, first and third graph.
Second, the graph of the population has only one turning point, that us, it has only one point where it changes from increasing to decreasing, that only let us the third option, because the first graph has to turning point like a wave.
Therefore, the third graph is correct.
