Your friend comes to you with a problem. It seems his shrimp boats arenʹt catching nearly as much shrimp as they used to. He canʹt understand why because originally he caught all the shrimp he could handle. Each year he added a new boat, and for many years his entire fleet came back full. As the years went on and he continued to add more boats, there came a time when each boat caught somewhat fewer shrimp, and now, each boat is returning only half full. Which of the following relationships might help your friend understand the source of his problem? Select only ONE answer choice.
A) density-dependent population regulation and intrinsic characteristics of populationgrowthB) exponential growth curves and unlimited environmental resourcesC) density-independent population regulation and chance occurrenceD) pollution effects of a natural environment and learned shrimp behaviorE) a K-selected population switching to an r-selected population
