What are services composed of?

A service is like a special job someone does for you, just like your friend helps you build a tower with blocks.

A service has two main parts: the person doing the job and the job itself. Think of it like when you go to the store to buy ice cream, the store is doing the service of selling you ice cream. The store gives you what you want, just like your friend helps you stack blocks.

Sometimes, a service needs help from other services. It's like when you want to make a sandwich, one person gives you bread, another gives you cheese, and another gives you jam. All these people are doing their own services, but together they help you get your favorite sandwich!

Services can be simple or complicated, just like playing with blocks can turn into building a whole castle. The important thing is that someone is always helping you out, one piece at a time!
