The population density of Tridex in an abandoned square farm land of side 200 m was found to be 5 plants per m\(^2\). The population size of the plant on the farm is
40
1000
40000
200000
설명
To estimate plant population size on farmland, you can use the formula: Plant Population density = \(\frac{(population size)}{(Area of habitat)}\)
Given:
Population density = 5
Area of farmland = 200m x 200m = 40000m\(^2\)
Population size = ?
Population size = population density x Area of farmland
= 40,000 x 5
= 200,000
