Document Summary

The collapse of easter island- looking at how many resources they had and estimate how many people the environment could sustain. Population growth - (birthrate and death rate) dn/dt = birth rate - death rate, Maximum number of individuals- frog has certain biological needs, of food it needs. Given area- shallow pond with large surface area vs. deep pond with little surface area, surface area would be the limiting factor of space to lay eggs. Crude birth rate (number of births and deaths per 1000 people) Crude death rate (number of births and deaths per 1000 people) Total fertility rate (the total number of children born to women between the ages of 15 and 55) Age structure and population momentum- shows the number of people in age"s classes young to old, male versus female, and it measures number of people in particular gender in age class.
