use of sampling in biology

1) Why do biologists use sampling? Why can't they just go into a habitat and count all members of the population of interest?

 

2) Population sampling is usually more effective when the population has an even dispersion pattern. Clumped dispersionpatterns are the least effective. Explain why this would be the case.

 

3) In a forest that measures 5 km by 5 km, a sample was taken to count the number of silver maple trees. The number of trees counted in the grid is shown in the attachmentScreen Shot 2017-09-19 at 11.53.55 PM.png. The grids where the survey was taken were chosen randomly. Determine how many silver maple trees are in this forest using the random sampling technique. Show your work!
