What is Symbiosis ?
Interaction between two different organisms living in close physical association, typically to the advantage of both and a mutually beneficial relationship between different people or groups.
Examples.
An example of symbiosis in a tropical rain forest is the relationship between the strangler fig and the trees that make up the rain forest. The strangler fig germinates in the leaves of the trees. From the tree tops, the strangler fig sends down aerial roots down to the ground that thicken into trunk-like structures that wind around the tree and strangle and kill it.
