Symbiosis is essentially any process where some organism depends directly on at least one other for resources vital to its survival. For instance, the HIV virus can't exist without an animal host. If you extracted it from the body and placed it on a tabletop it would die quite quickly. A fetus also can't exist without the mother. Both the HIV virus and a fetal animal require a symbiotic relationship with their host in order to survive... however one symbiotic relationship is very different from the other.
