In biology, there are some different kinds of relations between species.
For example:
Mutualism is the way two organisms of different species exist in a relationship in which each individual benefits from the activity of the other.

Symbiosis is close and often long-term interaction between two different biological species.

In ecosystem
predation is a biological interaction where a predator (an organism that is hunting) feeds on its prey (the organism that is attacked)

In biology/ecology,
parasitism is a non-mutual symbiotic relationship between species, where one species, the parasite, benefits at the expense of the other, the host.

How can we compare economic relations to those inter-species relations in biology?
For example: in the economic relations between different countries, can we trace any parallels to those kinds of inter-species relations?
