Your friend comes to you with a problem. It seems his shrimp boats aren’t catching nearly as much shrimp as they used to. He can’t understand why because originally he caught all the shrimp he could handle. Each year he added a  new  boat,  and  for  a  long  time  each  boat  caught  tons  of  shrimp.  As  he  added  more  boats,  there  came  a  time when each boat caught somewhat fewer shrimp, and now, each boat is catching a lot less shrimp. Which of the following topics might help your friend understand the source of his problem?
