Answer:the population density of chipmunks in 2021=256,666.667 per square kilometres
Explanation:
Population density is defined as the number of population per unit area of land
which can be expressed as
Population density =number of population/ land area
Since land area is usually given in square kilometres or square miles we convert 900 square meters to square kilometres
1 square kilometres =1000000 square meters
900 square meters=900/1000000=0.0009 square kilometres
Therefore, the population density of chipmunks in 2021= 231/0.0009 square kilometres =256,666.667 per square kilometres
