The author infers that more plant species (X) causes greater ability to support plant life (Y) based on the correlation observed in the study between more plant species (X) and greater ability to support plant life (Y).

The author doesn’t need to describe the causal mechanism. A causal claim can be supported by evidence, even if the author never describes the mechanism underlying the causal relationship.

There’s nothing flawed about thinking that one prairie plot can reveal something about others; if that plot is similar to other plots, it can still reveal something about others. Also, the study evaluated multiple plots; it wasn’t based on just one plot.

We have no reason to think that the plots involved in the study are likely to be unrepresentative of prairie plots.

The study showed that the more plant species in a plot, the better the plants grew. This doesn’t tell us there was an “increase” in plant species in any plot. In addition, the argument never asserts anything about the proportion of plant species or plants.
