Guide to food chain (top to bottom): osprey, pike, perch, smelt, freshwater shrimp. Which population would show the quickest increase if perch were eliminated from the food chain ? A) pike B) smelt C) osprey D) freshwater shrimp

Answer 1

It would be the smelt. Because the perch wouldn't be able to eat it. So the smelt would increase because there are less predators.
