Question

Describe the sampling method for determining population size.

Answer 1

Answer:

The sampling method comprises counting the entire number of organisms in a specific region and then utilizing the same number to find the entire number of organisms in a bigger region. A sampling method refers to a process of choosing sample members from a population.  

The three general sampling methods used in determining the size of the population are stratified sampling, simple random sampling, and cluster sampling.  

Answer 2

Some methods of determining the size of population are direct and indirect observations, sampling, and mark-and-recapture studies .

Sampling - Done by counting the animals in a small area and then estimating how many are in the larger area. You go out and take samples from different places so you can take the average. In most cases, it is not possible to count every member of a population so an estimate is made.

Mark and recapture - Another estimating method is a technique called "mark and recapture." This technique gets its name because some animals are first captured, marked, and released into the environment. Then another group of animals is captured. The number of marked animals in this second group indicates the population size.

Indirect observation - The members of a population may be small or hard to find. It may be easier to observe their tracks or other signs rather than the organisms themselves.

Direct observation - The most obvious way to determine the size of a population is to count, one by one.
