In a field having an area of 3.0 ha is a colony of ground squirrels with 90 members. What is the density of the ground squirrel population?
A. 90 ground squirrels.
B. 270 ground squirrels/ha.
C. 30 ground squirrels/ha.
D. 0.030 ground squirrels/ha.
If you need to find the density per ha, wouldn't you divide 90 by 3?
Oh so if it is ha all i need to do is that? divide everything by 3?
sorry i didn't learn what ha is
From Dictionary.com:
"a unit of surface, or land, measure equal to 100 ares, or 10,000 square meters: equivalent to 2.471 acres. Abbreviation: ha "
See -- I gave you an answer. <g>
To calculate the density of the ground squirrel population, we need to divide the number of ground squirrels by the area of the field.
The given information tells us that there are 90 ground squirrels and the area of the field is 3.0 hectares.
To calculate the density, we divide the number of ground squirrels (90) by the area (3.0 hectares):
Density = Number of ground squirrels / Area
Density = 90 ground squirrels / 3.0 ha
Simplifying the expression, we find that the density of the ground squirrel population is 30 ground squirrels/ha.
Therefore, the correct answer is C. 30 ground squirrels/ha.
