The relationship shown in the graph is not a relationship I would expect to find in nature. I do not think this phenomenon is possible in nature because the graph shows that local species richness is higher than the regional species richness at all points on the line. The two X axes are set equal to each other and the slope of the line is higher than one, making local richness higher than regional richness. Since the local area is a part of the regional area, having a local richness that is higher than the regional richness is not possible. The number of species found in the local area would factor into the number of species in the regional area, constantly making the regional species richness higher than the local species richness.

Topic Sentence
While it is clear you are talking about a graph that is comparing local and regional species richness, some background on the graph would have been helpful. Maybe next time include a little summary of what the graph says in your topic senetnce to allow for an easier understanding of what's going on.
This paragraph is well
This paragraph is well written and very informative. The only suggestion I have is to refer to a figure or graph that this paragraph is referencing.
seems like an
This reads more like an answer to a question rather than a paragraph. Like the comment above said, it would benefit from a topic sentence that explained what the graph was showing. Explaining species richness would also be helpful.
