Document Summary
Rsource accumulation is to match the challenges of the environment so you can grow, but its also to put into the bank that you can later use for sex.

Dependency ratio is looking at the number of infants and old people divided by the number of the producers. With age structure we break down the population of 24, where the 24 might comprise 9 babies, only some make it to childhood, some make it to become mothers. Through life individuals more from each stage to the next. Different time scales are used for different organisms.
