Ivan

For 2,000 mice living in a field, the per capita growth rate is mathematically given as

NT=0.4

<h3>What is the per capita growth rate (rmax) of mice over a month?</h3>

Generally, the birth and death rate is mathematically given as

BT=1000/2000

BT=0.5

Where

DT=200/2000

DT=0.1

In conclusion, per capita growth rate

NT=0.5-0.1

NT=0.4
