How do scientists count a species' population?

Answer 1

Maya Anderson

Counting them in a certain area and multiply that by the total area.

They will count the number of organisms in a known area, such as five sheep in a 1000 m^2 area.

They are attempting to determine the 20,000 m^2 total number of sheep in the nation.

Then they just take the average that they counted and multiply it by #20000/1000#.

So in this example the amount of sheep's total would be #5* (20000/1000) = 100#
