Question 101
XL-TMSQ2 marksNeeds review
In rivers that range in salinity (ppt) from low to high, researchers find that the aquatic snail species P (solid curve) and Q (dashed curve) were distributed according to the pattern illustrated in figure (i) when the species are together. The researchers then conducted a manipulative experiment in similar rivers with the same salinity range, where they removed either species P or Q. Figure (ii) illustrates the number of individuals of species P and Q when they were allowed to live alone. These snails have no other competitors or predators. Which one or more conclusions can be drawn from these two figures?
