If there are 40 turtles in a 5 km2 area, what is the population density? a. 8 turtles per km2
b. 40 turtles
c. 40 turtles per km2
d. 200 turtles

A

Explanation:

Population density is usually the number of subjects over the unit of area measurements. Thus, in this scenario, we set up the proportion of 40 turtles for every 5km^2 which can be simplified to 8 turtles every 1 km^2 which is answer A.

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.

looks like the answer is     c     to me!
