loblolly pine trees

Explanation:

Population density refers to the amount of organisms living in a particular area:

Population density = $\frac{number of organisms}{Area}$

Area of the forest = 10acres

Population densities of:

White-tailed deer = $\frac{8 white tailed deer}{10acres}$

= 0.8white tailed deer/acres

Coyotes = $\frac{7 coyotes}{10acres}$ = 0.7coyotes/acres

Armadillos = $\frac{45 armadillos}{10acres}$ = 4.5armadillos/acres

loblolly pine = $\frac{231loblolly pine trees}{10acres}$ = 23.1loblolly pine trees/acre

The population with the highest density is that of the loblolly pine trees with 23.1 of the trees in an acre.
