4.3 Explain how quadrats can be used to sample the distribution of organisms in their habitats.

• Quadrats placed in different areas at random
• One is chosen
• Population counted (must be either plants or VERY slow moving animals i.e. slug)
• Repeated in different areas
• Population counted
• You can compare results and see where population is more dense (i.e. there might be more flowers near a river bed)
