Order the process through which data makes its way from a service to an HTML view:
component makes a call to a service requesting data
service receives call from component and collects data
service sends data to component
component passes data to view
view receives data
view iterates through the data using *ngFor

you are not supposed to answer your question ,Q&A literally doesn't mean you write question with an answer to them as well,it's for asking doubts you have related to programming in hope someone has an answer to it ,however if you don't get answer to a real queries for some hours you can update your question to add the answer,so hopefully you will delete all these self answered questions.
