There is a 100 square meter rectangular meadow that has a rare plant growing throughout it.This plant species is used by a butterfly species as food and land managers are worried that the population of this plant may be too low to sustain the butterfly.Since there are no data about the abundance or density of this plant,you need to sample this field to determine its density and abundance.To best sample it,you should:
A) Chose one specific patch of the meadow and sample what is in it and assume the rest of the meadow is the same
B) Section the meadow into smaller units and chose to sample only the units on one side of the meadow
C) Section the meadow into small units and use a random number generator to sample some of those units
D) Cut down part of the meadow and let it grow back, the record the density and abundance of the plant

To obtain a representative sample of the meadow, it's best to section it into smaller units and use a random number generator to select which units to sample. This method helps to ensure that all parts of the meadow have an equal chance of being sampled, and thus provides a more accurate estimate of the plant's density and abundance throughout the entire meadow. Choosing one specific patch or sectioning off only one side would both introduce bias in the sampling, while cutting down part of the meadow would be destructive and not necessary for obtaining accurate data.
