A plаnt's rаnge hаs shrunk оver the last 40 years. Researchers identify twо impоrtant changes that have happened in the area over that time: 1) water has become less available and 2) a potential competitor has become more abundant in the area. They are interested in knowing which of those two is responsible for the change in the plant's range. They set up an experiment using 4 different conditions in an area where the plant used to be found but is outside the current range. unaltered plots (dry, competitor present) greater water availability (added water, competitor present) exclusion of competitor (dry, competitor removed) greater water availability and exclusion of competitor (added water, competitor removed) Their experiment is well-designed and carried out flawlessly (I'm skipping all the details so you don't have to read so much; the details aren't relevant to answering this question.) Based on these results, what seems to be limiting the current range of the plant?
