4.2 explain how quadrats can be used to estimate the population size of an organism in two different areas

A square of around a meter takes a sample from a area and the populations are counted. This can be repeated many times before being multiplyed out as if it were the complete area of the land. Two different samples can be put in two separate areas and the sampling done for both will estimate population for both areas.
