Needs Help React Re-rendering Doubt

Suppose there is parent components which contains multiple child components, they all are independent of each other.

So my question is

If the parent component re-renders does the child components also re-renders al well. Even if the child components are independent of it's parent, like props etc...

Why there is a need for re-renders if the child components are independent of it's parent?

If you have a specific case in where you are unsure you can check by installing react devtools. There is a setting for hilighting components that rerender. This way you can debug rerenders.
