Question

The snowy owl lives in the tundra, a cold biome in North America. In the year 2000, there were 200 snowy owls in a sample of the tundra. In the year 204, there were only 126.

Calculate the change in the snowy owl population size

Answer 1

18.5

Step-by-step explanation:

We are given that there were 200 snowy owls at first and then after four years, the population dwindled to 126.

The difference is 200-126, or 74.

There was a gap of 4 years, and it's a constant rate, so our answer is 74/4, or 18.5.

Answer 2

Step-by-step explanation:

In 2000 there were 200 snowy owls and in 2004 there were 126 snowy owls .

so, the number of snowy owls decreased is : (200-126)

= 74

now this number has decreased in 4 years . so per year decrease is : (74/4)=18.5
