Question

How do scientists count a species' population?

Answer 1

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

Explanation:

They will count the amount of organisms in a certain known area. For example they count 5 sheep's in `1000m^2`

They are trying to find the amount of sheep's in the whole country, which is `20,000m^2`

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`
