Which area would have the most species diversity? a large desert island a small island with a central mountain a large island with a mountain an island with a lake, mountain, and rivers in the north atlantic ocean an island with a lake, mountain, and rivers in the tropics?

Species diversity refers to the number of various species, which are demonstrated in a given community. The effective amount of species signifies the amount of equivalent plentiful species required to attain the same mean proportional profusion of species as that witnessed in the dataset of concern.

The species diversity comprises three constituents: taxonomic or phylogenetic diversity, species richness, and species evenness.

Species richness refers to the basic count of species, species evenness signifies how equal the abundances of the species are, and taxonomic or phylogenetic diversity refers to the genetic association between distinct groups of species. Thus, the correct answer is an island with a lake, mountain, and rivers in the tropics will have the highest species diversity.

sheep is a herbivore animal whereas grasshopper belongs to the class chordates but both of them feed on greens.  

if grasshopper and sheep feeding on a pasture land, i do not think both of them will have any impact on each other. however, the number of the species can make difference. since sheep feed on greens, there is a possibility there left no pasture land for the grasshoppers or they may get extinct.
