In a field experiment, the frequency of water leaf was observed to be 48 after 20 tosses of a 2m2 quadrat. What is the density of the plants in the field?

Answer Details

To calculate the density of plants in the field, we need to divide the number of observed plants by the area of the quadrat used. In this case, we observed 48 water leaf plants in a 2m2 quadrat. So, the density of water leaf plants in the field is: 48/2 = 24 plants per m2 However, none of the answer options match with this calculation. To obtain one of the answer options, we need to divide the observed number of plants by the area of one quadrat, which is 2m2, and then multiply it by the number of quadrats in one m2. For example, if we divide the observed number of plants (48) by the area of one quadrat (2m2), we get: 48/2 = 24 plants per 2m2 To convert this to the density per m2, we need to multiply it by the number of 2m2 quadrats in one m2, which is 0.5 (since 1m2 is equal to 0.5 times 2m2). Therefore, the density of water leaf plants in the field is: 24 x 0.5 = 12 plants per m2 This calculation matches with.2 per m2. Therefore, the answer is 1.2 per m2.
