Answer 2

Hi there!!!

The dark and light bands on trees represent their life span too...

Because, literally the light bands represent their life time in spring season and vice versa for the dark bands in autumn season.

This can also be used to represent their life span.

Each two [ dark and light bands] are used to represent 1 year in their life time.......
