A desert lake has evaporated to half its original size over the past 50 years. This caused a large increase in the lake’s salt concentration. Over these 50 years, scientists have observed a decrease in the population of one fish species and an increase in the population of a shrimp species. Which hypothesis about the organisms ability to live with the salt concentration does the evidence support?

The fish are better able to live in areas of high salt concentration
|
|
|
Neither the shrimp nor the fish are able to live in areas of high salt concentration
|
|
|
Both the shrimp and the fish are equally able to live in areas of high salt concentration
