The results are below Plot Native alga Exotic alga Wet: native only Grew well n/a Wet: exotic only n/a Wet: both algae Grew well Went extinct Dry: both algae Went extinct Grew well Grew well You note that his experimental design is incomplete and, as a result, he cannot support one of the following conclusions. Which conclusion is NOT supported? The native alga's fundamental niche includes wet habitats. The exotic alga's fundamental niche includes wet habitats. The exotic alga competitively excludes the native alga in dry habitats. The native alga competitively excludes the exotic alga in wet habitats.

Explanation / Answer
