4.3 explain how quadrats can be used to sample the distribution of organisms in their habitats.
A sample square is taken at random. The number of a population in that square is taken. This is repeated in different areas and compared to show where populations are dense and not.
quadrats should be placed randomly so that a representative sample is taken you should look at the results from several quadrats in an area to reduce the effect of an unusual distribution the results are more reliable when you look at the results from many quadrats quadrats may also be used for slow moving animals such as snails/slugs
