hey guyz!
I got a question!
It says that we need to define the 3 types of industries...
Frankly I kno them but I cant quite explain them for an IGCSE level...
The three industries are primary, secondary and tertiary.
How can I explain them properly?
Thank You for ur time 

I would really appreciate if all of u ppl would decrease my rep 

Im trying to make a new record
