What is the percent loss of species on island A, according to the chart
A. 12.5%
B. 14%
C. 25%
D. 30%
Percent loss= (25)/175 x 100
B 14 percent.
To calculate the percent loss of species on island A, we need to compare the initial number of species to the number of species after extinction.
According to the chart, the initial number of species on island A is 175, and the number of species after extinction is 25.
To calculate the percent loss, we can use the following formula:
Percent loss = (Number of species lost / Initial number of species) * 100
Number of species lost = Initial number of species - Number of species after extinction
Number of species lost = 175 - 25 = 150
Now, substitute the values into the formula:
Percent loss = (150 / 175) * 100
Calculating this expression:
Percent loss = 0.857 * 100
Percent loss = 85.7%
So, the percent loss of species on island A is approximately 85.7%.
