Question

How many golds are believed should die before age one?

a) 100
b) 1,000
c) 10,000
d) 100,000

Answer 1

The correct answer to the estimated number of extinctions in a century, using the extinction rate of 100 E/MSY for 10 million species, is 100,000 extinctions.

Step-by-step explanation:

Assuming the typo in the student's question refers to the extinction of species, not "golds" as mentioned, the calculation to estimate the number of extinctions expected in a century when the extinction rate is 100 extinctions per million species per year (E/MSY), with an estimated 10 million species is as follows:

Extinction Rate × Number of Species × Number of Years in a Century = Estimated Number of Extinctions.

Therefore, using the figures provided:

• Extinction Rate: 100 E/MSY
• Number of Species: 10 million
• Number of Years in a Century: 100 years

So the calculation is:

100 E/MSY × 10,000,000 species × 100 years = 100,000,000 extinctions expected in a century. The correct answer is d) 100,000
