Based on the data provided;
- Estimated population of Barnacles in A is 1128 Barnacles
- Estimated population of Barnacles in A is 1365 Barnacles
- the population density of Barnacles in B is greater than that in A.
What is a population density?
Population density is the number of organisms per unit area of a given geographical area or location.
Population density gives an idea of how densely or sparsely populated a given area is.
- Population density = number of organisms/area of land.
The area of quadrant = 1 m × 1 m = 1 m^2
Total number of Barnacles in 6 quadrant sample A = 13
Average = 2.17
Population density = 2.17/1m^2 = 2.17 /m^2
Total number of Barnacles in 6 quadrant sample B = 39
Average = 6.5
Population density = 6.5/1m^2 = 6.5 /m^2
Area of A = 20 m × 26 m = 520 m^2
Estimated population of A = 520 m^2 × 2.17 /m^2
Estimated population of Barnacles in A = 1128 Barnacles
Area of B = 14 m × 15 m = 210 m^2
Estimated population of Barnacles in B = 210 m^2 × 6.5 /m^2
Estimated population of Barnacles in B = 1365 Barnacles
From the above results, the population density of Barnacles in B is greater than that in A.
