hi lovely and helpful people !! :)

I need your help. Today in biology class we conducted experiment pertaining to Lincoln Index ( which measures estimate of population).

Teacher asked us several questions that I am not sure how to answer. We were working on seeds of beans. May I relay on your help?? These are questions:

1) Why did the estimate of number of individual in population ( counted by Lincoln Index) differ from exact count of the population of beans ? Discuss some of the factors that might affect the accuracy of your estimates.

2)Why is it important that the times between the first and second samples be a short time compared to the organims's life span?

3) How did immigration and emmigration affected your population??

4) How can a data collector determine whether the population being studied is growing or declining??
