I know you folks can do this one, lots of options. I was also corrected on my definition of symbiotic by my lovely girlfriend who needs to remember she's an engineer now not a biologist, you've been converted.
Anyways I guess they don't both have to benefit as there are three types of symbiotic relationships. I'll probably be corrected again but:
1) Both benefit
2) One benefits
3) Neither benefit
I would love to see examples of all these! Oh and if you disagree on the definition let me know cause I love feeding the fire
