One way is what is called a "Mark-Recapture" a study on how large the population is.

By Genocide, and by war..
you can just go and count all of them stupid!
There are many different ways, such as dying out or being alone with no mate.
I realized that fapping is the best.
Sampling - counting the number of organisms in a small area and multiplying to estimate the number in a larger areaMark & Recapture - capture an organism & release it to remix with population. Then recapture some more in that area to determine population size. Formula is as follows: R (marked recaptures) / C (total in second sample) = M (marked initially) / N (total pop. size)Indirect Observation - estimating the population size by tracks, nest or other animal signs in an ecosystem.Direct Observation - count all members of a population in an ecosystem
A) Another Genocide (The Holocaust) B) A really big Asteroid
Ecologist study population by mark and recaptur tagged and released.

Two ways to leave a population are through emigration, where individuals move out of the population to live elsewhere, and through death, which reduces the population size by the loss of individuals.
Size
Several ways.By its size, orientation, colour, luminosity are some possible criteria.Several ways.By its size, orientation, colour, luminosity are some possible criteria.Several ways.By its size, orientation, colour, luminosity are some possible criteria.Several ways.By its size, orientation, colour, luminosity are some possible criteria.
