Based on Figure 53.4, what percentage of the female Belding's ground squirrels survive to be 3 years old?

  • A: 5%
  • B: 10%
  • C: 20%
  • D: 50%

Explanation

The graph in Figure 53.4 shows the number of survivors on a logarithmic scale. At age 0 years, there are 1000 survivors. At 3 years of age, the red line is approximately at the 100-survivor mark on the y-axis. Therefore, the percentage of survivors is 100 / 1000 100% = 10%.
