Calculations: a. Calculate the percentage frequency [5]

` Percentage frequency =( Total number of quadrat(s)/(s)egments in which species occurred )/( Total number of quadrat(s)/(s)egments studied )\times 100`

b. Distribute various species into five frequency classes (Raunkaier, 1934) as given below. [5] \table[[\table[[Frequency %,Frequency class],[

Write out how many species fall in to different frequency classes. [5] 6 \table[[Frequency class,No. of species],[A,-],[B,-],[C,-],[D,-],[E,-],[Table 4:Observed distribution in frequency classes,]] Table 4:Observed distribution in frequency classes e. Use your answer in d. above to find out the percentage of these species falling into different frequency classes as follows out of the total number of species recorded. [5]

`( No. of species falling in frequency class? )/( Total number of species recorded )\times 100`

i. For frequency class

`A=`

ii. For frequency class

`B=`
