Answer:
See the procedure
Step-by-step explanation:
we know that
To find the population density per m² of each of the above species, divide the amount of each species by the total area
so
Ferns
[tex]\frac{30}{15}=2\frac{ferns}{m^{2}}[/tex]
Grass plants
[tex]\frac{150}{15}=10\frac{grass\ plants}{m^{2}}[/tex]
Oaks Trees
[tex]\frac{6}{15}=0.4\frac{oaks\ trees}{m^{2}}[/tex]
