How can resources limit the number of wants people and businesses can satisfy?

A customer will have wants and needs. A need is anything you need to survive:

water

food

shelter

warmth

food

A want is evrything else:

A watch

A pony

An ipad

A TV

A car

Business seeks to satisfy customers needs and wants. Think about a supermarket it will sell things people need - water, food, etc and things people want - wine, DVDs, jewellery etc

Resources are anything that is used to make a good ( a product) or provide a service (like gardening or cleaning, something you can't touch.)

When resources are scarce ( in short supply, running low) then customers wants cannot be satisfied. For example you go to the shops to buy strawberries for dinner BUT there has been a bad summer and a poor strawberry crop. The strawberries are in short supply and the supermarket has run out. You cannot satisfy your need for strawberries!
