An ecologist counts 75 cardinals in an area measuring 15 square kilometers. what is the population density of the cardinals?

5

Explanation:

We know that,

number of count of cardinals = 75; and

measured area = 15 square kilometers.

To find the population density of the cardinals in an area of 15 square kilometers, we need to divide the number of cardinals by the given unit area:

Population density of cardinals = 75 / 15 = 5

Therefore, the population density of cardinals in an area measuring 15 square kilometers is 5.

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.
