Refer to the graph presented below and answer the questions that follow:
- Define the concept of species’ richness and species’ evenness.
Species richness is a count of number of different species in a given area. The more species found in an area, the richer it is.
Species evenness is the relative number of individuals among the taxa (proportion)
- Explain the shape of the graph.
This is a type B graph that says species richness increases with increasing number of individuals encountered. The first species encountered is most likely to be a common one. Then the occurrence of meeting the rare one increases as time progress.
- How might an ecosystem with a higher species diversity look like compared to the graph shown above?
