GENERAL KNOWLEDGE

IN A FIELD EXPERIMENT, THE FREQUENCY OF WATER LEAF WAS OBSERVED TO BE 48 AFTER 20 TOSSES OF A 2m^2 QUADRAT. WHAT IS THE DENSITY OF THE PLANTS IN THE FIELD

  • A. 1.2 per m2   ✓
  • B. 2.4 per m2
  • C. 4.8 per m2
  • D. 9.6 per m2

 

The answer to the question is: A. 1.2 per m

Calculating Plant Density

To calculate the density of the plants in the field, we can use the formula:

Density = Number of individuals / Area sampled

Given that the frequency of water leaf was observed to be 48 after 20 tosses of a 2m² quadrat, we can calculate the density as follows:

Density = 48 / 20 × 2 = 48 / 40 = 1.2 per m²

Therefore, the density of the plants in the field is 1.2 per m².
