Question 9

The data to estimate the plant biodiversity in a meadow was collected using the following method:

  • A 150 m2 section of the wildflower meadow was marked out.
  • Two 1 m2 quadrats were placed randomly on the ground.
  • Wildflower plants inside each quadrat were counted.
  • The number of individuals of each plant species was recorded.
