1. Find out how members or teams in your country share a symbiotic relationship and depend on each other to reach a shared goal.
Note that some people offer a service and have clients pay for that service. For example, a store owner and customer are NOT a symbiotic relationship.

There are teams in sports, business, medicine, etc.
The word team means group of people who share a particular goal and work together to achieve those specific goals.
