In the diagram, Which of the following can be decided from the distribution?

Answer Details

From the distribution shown in the diagram, we can decide that species IV is the one whose distribution is not dependent on rainfall. Species IV is found in all three locations, regardless of the amount of rainfall, whereas the other three species are restricted to specific areas based on rainfall levels. This suggests that species IV may have adaptations that allow it to tolerate a wider range of environmental conditions than the other species. However, we cannot make any conclusions about the rainfall preferences of the other species based on this diagram, as their distributions are not as clear-cut. While species III seems to be most abundant in the location with the highest rainfall, it is also found in the other two locations. Similarly, while species I and II are more restricted in their distributions, we cannot definitively say whether they prefer moderate to high rainfall or constant rainfall based on this diagram alone.
