PLEASE ANSWER CORRECTLY I AM A PAID MEMBER. I DIDNT PAY TO GET WRONG ANSWERS!!!!!

1. Make a prediction: how many photo quadrats should you take in order to estimate the alpha diversity (number of species) on an underwater rock wall?

A) Take photo quadrats that sample the whole area of the rock.

B)Take photo quadrats until the first photo showing no new species. (A "new" species here is one that was not in a previous quadrat.)

C)Take photo quadrats until several photos in a row show very few new species.

D)Take only a few photo quadrats. Then multiply the number of species found in that small area by the full area of the rock.

Explanation / Answer

D)Take only a few photo quadrats. Then multiply the number of species found in that small area by the full area of the rock-This is the correct format because when a small section of rock alone is specified,the number of species can be sampled and a cler idea of species can be obtained.

An assumption that the small section of species would be present in the remaining rock area,the small area is multiplied with full area which also saves time inspite of examining the entire rock structure.
