9PRACTICE PROBLEM

A group of students was tasked with collecting data on flora and fauna of a nearby mangrove forest. They assessed the diversity and abundance of mangrove species in three study areas. In each study area, they set three 10 m x 10 m quadrats at a distance of 15 to 30 m from each other. Based on this data, the following graph shows the number of individuals of different genera.

What is the most abundant genus in the sampled areas?

10PRACTICE PROBLEM

A class of students was tasked with collecting data on flora and fauna in a nearby mangrove forest. One group assessed the diversity and abundance of mangrove species in the area. In each area, they set three 10 m x 10 m quadrats at a distance of 15 to 30 m from each other. They assessed a total of three areas. Based on the given information, what is the total area sampled by the students?
