Well I do not know what they are talking about
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
Answer:
The moths would decrease.
Explanation:
Before the birds were introduced in the new habitat, there were many moths. But now that there are predators for moths, the moths would decrease and will not reproduce as much to make more moths.
Hope this helped!
