Answer:
It's an advantage for the bacteria, not an advantage for the salamander
Explanation:
The point of reproduction ideally is to produce as many offspring in as little time as possible, to increase the number of offspring that thrive. Therefore the bacteria being able to multiply quickly is an advantage and will most likely increase the chances of evolution occuring sooner (antibiotic resistant bacteria for example). The salamander having to wait 4 years to have few offspring will make the number of babies they're able to have in a lifetime rather low.
What might occur to its symbiotic match if commensalism abruptly evolved vanished?
Answer:
The Sun *emits* white light, which is actually a composite of all of the visible frequencies of light. (A prism shows you the visible frequencies of white light.) The distribution of solar frequencies is uneven, the most intense frequency is in the yellow-green part of the spectrum.
