What is the most common method used to count a large species population? A. Estimating B. Sampling C. Guessing D. A pencil and paper

Answer;

Estimating

Explanation;

A population consists of all the organisms of a given species that live in a particular area. Two important measures of a population are population size, the number of individuals, and population density, the number of individuals per unit area or volume.

Ecologists estimate the size and density of populations using quadrats and the mark-recapture method. The organisms in a population may be distributed in a uniform, random, or clumped pattern.

Option B is the correct answer.

Sampling is done for estimating a population's size by taking one or more samples from the population. Then these samples are used to make assumptions about the population as a whole.
