Fisher's exact test for this table?

#1
Hello!

I would like to do a simple test just to verify if I can analyse this table. It represents the number of animals from each species feeding on plants with different heights.
The aim is to verify if the bigger species always eat on tall vegetation (Species2 is the biggest, Species1 and Species3 almost have the same height).

Would a Fisher's exact test allow me to say that species and vegetation height are dependent? (and then would I be able to just state what is obvious in this table?)
Or maybe I don't need to statistically analyse this table because it is obvious?



Thank you!

Since the sample size is large it is obvious to me ...that the is a significant association between height and species.
But you should run the test to make it quantitative, otherwise, in some cases, people will decide "it is obvious" and it won't be correct ...
