There are an estimated 11,025 trees of species a in an area of 3,150 hectares. what is the population density of the tree species? the population density of the trees is _ per hectare.

Population density is the average number of organisms that make up a population per unit area or unit volume.

As given in the question; Number of organism (trees of species A) = 11,025 and land area = 3,150 hectares.  

Population Density = Number of organism / Land Area = 11025/3150= 3.5 trees/hectare.

Therefore, the population density of the trees is 3.5 trees per hectare.

the rocks are classified by the geological process they are formed by. the three main groups of rocks are igneous, metamorphic, and sedimentary. minerals are not they are classified under the chemical classes they are in. these groups include silicates, sulfates and carbonates.
