Question

80 POINTSSSSS

Over the years, separate teams of scientists have been tracking and studying different bird species in Africa. They want to know if certain bird populations have been increasing or decreasing over time. For 8 years, one team of scientists has tracked the African Fish Eagle. When their research began, there were 32,800 African Fish Eagles in Africa. Today, there are 43,952 African Fish Eagles living in Africa. Meanwhile, another team of scientists have been tracking the Tawny Eagle. Over the last 8 years, the population of Tawny eagles went from 7,900 to 10,981. Which eagle species saw a larger percent increase to their population over the last 8 years?

Answer 1

Tawny Eagle

Explanation:

Percent Change Formula

`\sf percent\:change=(final\:value-initial\:value)/(initial\:value) * 100`

African Fish Eagle

Given:

• Initial population = 32,800
• Final population = 43,952

`\implies \sf percent\:change=(43952-32800)/(32800) * 100=34 \%`

Tawny Eagle

Given:

• Initial population = 7,900
• Final population = 10,981

`\implies \sf percent\:change=(10981-7900)/(7900) * 100=39 \%`

Solution

Therefore, the Tawny Eagle species saw a larger percent increase to their population over the last 8 years.
