A frog population is living in the lake near the campus. After a field survey, scientists reported that there are estimated 650 frogs in the lake area (which is 130 squared meter in size).
The population density of this frog population is .

A. 650 frogs
B. 5 frogs per squared kilometer
C. 5 frogs per squared meter
D. 13 frogs per squared meter
E. 130 frogs

Option C.

5 frogs per squared meter.

Explanation:

Population density is the total number of organisms per unit area.

It is calculated as Population ÷ unit area.

The population of the frog = 650

The unit area = 130 square meter.

650÷130= 5.

The answer is 5 frogs per square meter.

Square meter can be used for small space or small area.
