This was a problem on the exam
There is species A and species B. They both feed on nectar. Species A feeds only during the day and Species B feeds only during the night. There is competition between A and B as their niche overlaps slightly. Both A and B can feed during day AND night if there was no competition.
There is a graph with the x axis being Time (from day to night) and Y axis being number of Nectar visits (or nectar use).
Species A has a much higher level of nectar visits than Species B and their niches overlap slightly.
Would this be an example of niche differentiation or competitive exclusion?
I first thought niche differentiation because A and B are using the nectar at different times to avoid competition, but at the same time, the niche of A and B overlaps slightly and species A has greater nectar use than species B. This would be a form of asymmetric competition and competitive exclusion would sound more likely. But then again, if both species A and B can use the nectar during BOTH day and night but are only excluded to using day or night to reduce competition, it sounds more like niche differentiation . WHICH ONE IS IT? Help someone? choosing best answer
here is a link to the graph I drew:

One, giant, festering hole in the theory of gravity is that physicists can’t explain *why* large masses attract smaller masses. They can explain how, but this little piece of missing knowledge is worse than the pffft, “theory” of evolution.
I mean, we all know it’s a fact that allelic frequencies vary in a population over time, and that those alleles which contribute to a species survival in it’s niche increase over time. We also know that the “theory” of evolution explains these observed facts. BUT, no one can explain *why* gravity works the way it does.
Take that gravitationists! It looks like the hundreds of thousands of biologists all over the world are on to something, while you’re just peddling what amounts to scientific smut. STOP teaching the lie of gravity in our schools!
Now, if you’ll excuse me I need to go slap my chest, try to bite my ear, and stick square pegs into round holes.
