Several scientists travel to a remote coast to study the biodiversity of the area. How could the scientists calculate the species richness of the ecosystem? A. counting the total number of different species

B. calculating the number of organisms in each trophic level

C. counting the total number of individual organisms

D. calculating the number of producers in the area

A. counting the total number of different species

Explanation:

The only way to calculate the species richness in the ecosystem is counting the total number of different species. This is basically what species richness is, therefore it would be the best way to calculate it. Species Richness does not require that the scientists take into account the population of each species instead, each unique species found is counted as 1 towards the calculation of species richness.

i think a) betsy can donate only blood to mark is correct because, mark and betsy have the same blood type. whereas nobody else has b+ blood so betsy can't donate to them.
