Question

table provides information about the populations of species in two communities. which has the greater species diversity? community x, because the community is richer community x, because the distribution of species is more even community y, because the total number of individuals is greater community y, because the community is richer

Explanation:

Step1: Calculate total number of individuals in each community

Community X: $15 + 18+12 + 20=65$
Community Y: $4+25 + 40+9 = 78$

Step2: Analyze species - richness and evenness

Species - richness is the number of different species in a community. Both communities have 4 species, so species - richness is the same. Species - evenness is the relative abundance of different species. In Community X, the abundances are $15,18,12,20$. In Community Y, the abundances are $4,25,40,9$. The abundances in Community X are more evenly distributed.

Answer:

Community X, because the distribution of species is more even
