Question

Many marine organisms depend on upwelling to bring nutrients to the surface. How might El Nino affect a fisherman's way of life?

Answer 1

It affects a lot because upwelling affects the movement of animal life in the area.As the temperature of the water changes then the position of the animal life changes.For example the developing forms of many fish and invertebrates are affected because it can wash the larvae far offshore, endangering their survival.
