Answer 2

Symbiosis is a close association of two organisms over a long period of time which may be beneficial for both the organisms, help one of them but not affect the other or help one of them and harm the other.

An example of a mutually beneficial symbiosis that has been going on for millions of years is that between insects for example bees and plants. Plants need to have their pollen propagated, so they produce nectar in their flowers. The insects feed off the nectar and propagate the pollen which sticks to their body.
