Question

Individuals of a plant species are counted in four transects that are each 2 x 3 meters. In these transects, 6, 15, 18, and 33 are found. What is the density per square meter of this species?

A. 2
B.3
C. 6
D. 18

Answer 1

The population density of the plant species is 3 plants per square meter, calculated by dividing the total number of individuals by the total area of the transects.

Step-by-step explanation:

To calculate the population density per square meter of this plant species in the study area, we first need to determine the total number of individuals counted across all transects and then divide by the total area surveyed. In this case, 6 + 15 + 18 + 33 plants were found in four transects each measuring 2 x 3 meters, which gives us a total of 72 plants within 24 square meters. To find the density per square meter, we divide the total number of plants by the total area surveyed (72 plants / 24 square meters = 3 plants per square meter). Therefore, the population density is 3 plants per square meter, which corresponds to option B.
