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

Explanation

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
