symbiosis
A symbiotic relationship involves 2 species livingtogether. Mutualism is when both benefit. Commensalism is when one benefits without harming the other. Parasitism is when one species benefits while harming--but not killing--the other. An example of parasitism would be a tick on a dog. If the dog died, it would stop pumping blood for the tick to consume. In predator-prey relationships, most often one party must die for the other to benefit.
The relationship between organisms is generally referred to as symbiosis. A symbiotic relationship where both organisms benefit is called mutualism (co-operation is the term used when mutualistic behaviours occurs between member of the same species). Other types of symbiosis are parasitism (one benefits and the other is adversely affected) and commensalism (one benefits and the other is neither positively nor negatively affected)
Commensalism is where one species benefits and the other is unaffected. Like a bee and a flower. The bee benefits because it gets the nectar from the flower. The flower is unaffected because nothing happens to it.
When two species evolve together, having some relationship while evolving, they both leave traces of what the relationship was in their genetics. For instance, if you see one species with huge teeth, and another with thick skin, one might draw the conclusion that the relationship encompassed one species trying to eat the other.
symbiosis
Commensalism refers to a kind of relationship where the other group of species is not harmed or affected while the other one benefits from the activities of the other group.
Commensalism is a relationship in which one species benefits. The other species not unaffected. An example would be when an animal uses a plant or tree for shelter. An American Robin benefits by making its nest in a Red Maple tree. The tree is not affected.

Parasitism :)
It's called a parasitic relationship when one species benefits and one species is harmed. A simbiotic relationship is when both species benefit.
The Polar bear is a giant apex predator and hence it shares a Predator - Prey relationship with other species.

Yes it has been affected
