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
