Figure 6. Population Distribution of Plants
Procedure:
1. Study the three (3) patterns of population distribution (Bermuc Cogon and
Makahiya) as shown in the Figure above. Solve for the area (A=LxW) given that the
Length is 20cm and Width is 20cm.
2. Count the number of organisms in each population and record it on the table given
below.
Using the given formula below, compute for the density of each population
DENSITY=
number of individuals
size of the area

Guide Questions:
Q1. Compare the distribution patterns of the three (3) populations.
Q2. Which population has the greatest density?
Q3. What are the possible causes for the difference in population density?
Q4. What are the factors that could change the density of each population?
