LEDCs consume less protein than MEDCs 9. The length of time is take for a population to double is called doubling time. 10. The collection of threatened species is on the red list. 11. What is the purpose of the Lincoln Index? It allows you to estimate the total population size of an animal in your study area. 12. What is the difference between total fertility rate and general fertility rate? Total: average number of births per women of child bearing age General: number of births per thousand women aged 15-49 13. What is the difference between conservation and preservation? Conservation is to spend of use sparingly. Preservation is to keep and maintain what you have.
