Symbiosis is a relationship between two organisms that's beneficial to one (commensal) or both (true symbiote). For instance, giant clams have algae living within them. They each recycle the other's waste products and supply their partner with nutrients. Symbiosis can exist between different kinds of organism, such as between plants and fungi or plants and animals, as well as between different species.
