Question

Assume a population comprising 40 individuals of frogs in the pond has grown into 80 frogs after one reproductive cycle in assumption of equal birth-death rate and no migration
a)what is population growth after one reproductive cycle
b) calculate rate of population growth

Answer 1

A) Population growth: "Final population"-"Initial Population"-We wanna see how many new frogs there are.
b) Rate of population growth: I might be wrong here, but is it "Final Population"/"initial population"?

Answer 2

I was given a formula R=(natality+immigration)-(eath+emigration)/ (initial population sizex100%) and R= (natality+immigration)-(death + emigration)/time taken for change to take place...but i don`t know how to apply the formula..

Answer 3

Natality-Births
Natality and immigration are the "rises" in the population.
Death and emigration are the reductions in the population.
I don't see how the formula could be applied here, as I can only see that a rise has occurred. You should state if there's any other info.
