An ecologist observes that the diet of a bird species consists primarily of large grass seeds (as opposed to smaller grass seeds or the seeds of other herbaceous plants found in the area). he hypothesizes that the birds are choosing the larger seeds because they have a higher concentration of nitrogen than do other types of seeds at the site. to test the hypothesis, the ecologist compares the large grass seeds with the other types of seeds, and the results clearly show that the large grass seeds do indeed have a much higher concentration of nitrogen. did the ecologist prove the hypothesis to be true? can he conclude that the birds select the larger grass seeds because of their higher concentration of nitrogen? why or why not? smith, thomas m.; smith, robert leo. elements of ecology (page 15). pearson education. kindle edition.
