Question:
What is the most classic example of symbiosis?



Replies:
Probably nitrogen-fixing bacteria on the roots of legumes (peas and beans and alfalfa). The bacteria convert nitrogen into a chemical form that the plant can use, the plant supplies the bacteria with sugar and other nutrients. This is an example of "mutualism", in which both symbiont and host benefit. The other 2 types of symbiosis are commensalism, in which the symbiont benefits without affecting the host one way or the other, and parasitism, in which the symbiont (the parasite in this case), benefits at the expense of the host.
