Apopulation of shrimp suddenly starts collapsing. a biologist believes that toxins in the food chain are interfering with larvae development. a climate scientist believes that a change in water temperature is depleting food sources from the water. why are both of these options valid scientific hypotheses?

Each explain a logical explanation as to why a population decrease would occur. Toxins would kill off prey or even predator, making populations drop. A change in temperature also explains a population drop as the current known species of the area wouldn't be able to cope with the sudden change. Hope this helped.

Because they make sense and they can be proved
