The number of plants species obtained from a population study of a garden is as follows: Guinea grass (15), Ipomea spp (5), sida spp (7) and Imperata spp (2...

Answer Details

To calculate the percentage of occurrence of Imperata spp, we need to divide the number of individuals of Imperata spp by the total number of individuals in the population, then multiply by 100. So, the total number of individuals in the population is: 15 (Guinea grass) + 5 (Ipomea spp) + 7 (sida spp) + 23 (Imperata spp) = 50 The number of individuals of Imperata spp is 23, so the percentage of occurrence of Imperata spp is: (23 / 50) x 100 = 46% Therefore, the answer is 46%.
