You have two tree forest communities. Community 1 has 20 species and each species has exactly 100 individuals in their populations. Community 2 has 20 species with one species "Which community has a higher species richness"? A. Community 1. B. Community 2. C. Both have the same richness. D. There is not enough information to answer the question.

Option C, Both have the same richness

Explanation:

Given –  

Community 1 has 20 species with each species having 100 individuals  

Community 2 has 20 species with each species having 1 individual

This indicates that the species richness is the same in both the communities because species richness is defined by the total number of species in a given community. There is no relation between “species abundance with in a community” to the species richness.  

Thus, option C is correct

explanation:

primary succession occurs in essentially lifeless areas regions in which the soil is incapable of sustaining life as a result of such factors as lava flows, newly formed sand dunes, or rocks left from a retreating glacier. secondary succession occurs
