Okay you mongoloid I am going to lay this out for you as simply as possible.
Symbiosis is merely the term for when two different biological species have long-term interaction. The degree of interaction and what said interactions entail can vary from case to case.
Okay? Do you understand that much? Good, let's move on.
Let's look at the different types of symbiosis.
Parasitism is when one party benefits, and one suffers.
-Ex: Mosquitos, Fleas, Head Lice
Commensalism is when one party benefits, and one is neither helped nor harmed.
-Ex: Remora fish hitch rides on larger marine life forms to get to food.
Mutualism is when both parties benefit.
-Ex: Clownfish hide and stuff in anenomes, which they are immune to the stingers of. The anenome's stingers protect the clownfish from predators, and the fish stuff has nutrients that help the anenome.
Parasitism is a type of symbiosis. Therefore, symbiosis is not when two species benefit each other. The word you are looking for is
mutualism. What you're saying is like if I said "Vehicles have four wheels." Cars are a type of vehicle and have four wheels, but bulldozers are also a type of vehicle and they do not have four wheels, so "Vehicles have four wheels" is wrong.
Seriously. Do some actual research once in a while. Your habit of making up terms ("HYPERFRICTION YOU GUYS") and getting existing terms flat out wrong is just embarrassing.
