Question

moth graph percentage
during the fourth generation, 27% of the dark moths were captured from clean forest b. what percentage of moths were recaptured from polluted forest a during the fourth generation?
number of dark moths found in different forests
multiple choice

Explanation:

Step1: Identify data from graph

From the graph, for forest A at the fourth - generation, the number of dark moths captured is around 1100. For forest B at the fourth - generation, the number of dark moths captured is around 250. We are given that the percentage of dark moths captured from clean forest B is 27%. But we need to find the percentage from polluted forest A. However, we assume that the total number of moths recaptured is the sum of moths from both forests (a simplifying assumption as no other total information is given). Let's assume the total number of moths recaptured is \(T=1100 + 250=1350\).

Step2: Calculate percentage for forest A

The percentage of moths recaptured from forest A, \(P=\frac{1100}{1350}\times100\%\).
\[P=\frac{110000}{1350}\%=\frac{2200}{27}\%\approx 81.48\%\]
Since we don't have this exact value in the options and we assume some rounding - based on the context of the problem (if we consider the fact that the sum of percentages from both forests should be 100% given the information provided), if 27% are from forest B, then the percentage from forest A is \(100 - 27=73\%\) (a more likely assumption considering the simplicity of the problem and lack of other data).

Answer:

73%
