To find the unit rate of discovery, we need to determine how many species were discovered per year.
In the given information, it states that 4,000 new species were discovered in the last 2 years.
To find the unit rate, we divide the number of species discovered by the number of years:
Unit rate = Number of species รท Number of years
Therefore, the unit rate of discovery is:
Start Fraction 4,000 species over 2 years End Fraction
Simplifying this fraction, we get:
Start Fraction 2,000 species over year End Fraction
So, the unit rate of discovery is 2,000 species per year.
