Q4.16. Your colleague designed a common garden experiment to determine if moisture level influences competition between a native alga and an exotic alga. The design includes four plot types: dry with native only, dry with exotic only, dry with both algae, and wet with both algae. The results are below. Plot Native alga Grew well n/a Exotic alga Dry: native only Dry: exotic only Dry: both algae Wet: both algae Went extinct Grew well Grew well n/a Grew well Went extinct 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 dry habitats. The exotic alga's fundamental niche includes dry habitats. The native alga competitively excludes the exotic alga in dry habitats. The exotic alga competitively excludes the native alga in wet habitats.
