Correct Answer: Option D
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

There is an explanation video available below.
