Answer:
0.1
Explanation:
The Net Reproduction per individual per unit time (r) can be calculated as (births-deaths)/population size
Given that:
Population size of mice = 1,000; Birth = 500; Death = 400,
Net reproduction rate (r) = (births-deaths)/population size
r = (500 – 400)/1000
r = 100/1000
r = 0.1
The Net reproduction per individual per unit time (r) is 0.1
