Q1. Draw a figure which shows niche range distribution for some resourcefor 2 competitive species. Think about what resource the species competesfor and use that to set up your x-axis. Make sure you label the axes ANDthe tick marks AND write a figure legend.Figure 1.Competition between two species (nutrients and soil), where nutrients is thestronger species, more to the right with a larger curve, and soil is the weaker species,farther to the left with a smaller curve.Q2. Which pair(s) of species are competing most intensely?Species A and Bbecause they both have a similar amount of resources (most overlapped).
Q3. What are the signs for the fitness effects for this interaction? Describean experiment you could perform to determine if 2 species are competing.What would be the evidence that there was a competition?- / - both speciesare negatively impacted. If removal of one species improves the fitness of the other, it isevidence that they were competing.Q4. What do the data to the left illustrate about the two finch species?Something we see in different species that sometimes occur together, and sometimesoccur apart. Become more similar in their niche use in order to minimize thatcompetition.A. Traits are more similar where the species occur togetherB. Traits are more different where the species occur togetherC. Traits are determined by species, not location
Q5.True or False:In general, selection should favor more parasites thatare more lethal. Explain.If they have to be inside some host to live more generally,they are not going to be more beneficial if they kill them because then they don’t have ahost and have to search for another one (or die in the process).
