Question

Ecologists survey the tree species in two forest plots. plot 1 has six different species, and 95 percent of all trees belong to just one species. plot 2 has five different species, each of which is represented by approximately 20 percent of the trees. compared with plot 1, plot 2 has __________.

Answer 1

In this case, the plot 1 is very rich in the single species; it is dominated by a particular species, which occupy 95% share. While in the plot 2 are rich in the number of species, it has 5 species occupying 20% share.  

In comparative analysis, it is seen the plot 1 is rich in species, but diversity is very less. While, plot 2 is rich in the diversity of species, as 5 different species are present, but it is not rich in a particular species.

Hence, compared with plot 1, plot 2 has greater species diversity and lower species richness.
