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 (23). What is the percentage of occurrence of Imperata spp?
Total number of species = 15 + 5 + 7 + 23 = 50
Total number of Imperata spp = 23
Percentage occurence of Imperata spp = number of imperata/ total number of species X 100
= \(\frac{23}{50}\)\(\times 100\)
= 46% - Option C
There is an explanation video available below.
