Production Posibility Curve Introduction

The production possibility curve is a diagram that represents a opportunity cost of any goods of service

Diagram Example

Now lets take an example i am a person who catches fishes and plucks apples , the first day i caught 4 fishes and 100 apples but the second day i plucked 200 apples but caught 3 fishes , at the third say i caught 2 fishes and plucked 250 apples but at the fourth day i caught 1 fish and plucked 300 apples , so now lets see this at the chart :

As you can see here this was a diagram shown that how i managed my Business of plucking apples and fishing but lets look at the next diagram

As you can see i have marked a random day of me collecting 200 apples and collecting 2 fishes , it the type of production appears inside the chart it means that they are lacking resources and the dot you see outside which says collecting 250 apples and 4 fishes in a day which is impossible. The line you see from 4 to 300 are the most effiecient basically they are representing the best you can do.
