Which of the following activities is not necessary in population sampling?
Answer Details
Feeding the organisms is not necessary in population sampling.
Population sampling is a technique used by ecologists to estimate the abundance and distribution of different species within a given habitat. It involves selecting a representative sample of the habitat and then counting the number of organisms present within that sample.
The other activities listed - selecting the habitat, dividing the selected habitat into portions, throwing the quadrat randomly, and counting the number of organisms - are all necessary components of population sampling. Selecting the habitat involves choosing an area that is representative of the larger habitat being studied. Dividing the selected habitat into portions is necessary to ensure that the sample is representative of the larger habitat. Throwing the quadrat randomly helps to ensure that the sample is not biased in any particular direction, and counting the number of organisms is necessary to estimate the abundance of each species present within the sample.
Feeding the organisms, however, is not necessary for population sampling, as it does not contribute to the estimation of population abundance or distribution.
