! . which of the following would be the best way for an ecologist to determine the effects of an
industrial waste chemical on the survival of a fish species?
conducting experimental work in a lab
conducting library research
constructing mathematical models on a computer
observing the effect of increasing the amount of chemical in nature

Answer:

Observing the effect of increasing amount of chemical in nature would be the best way for an ecologist to determine the effects of an industrial waste chemical on the survival of fish.

Explanation:

Release of untreated effluents into water bodies pollute the water bodies and pose threats to the existence of aquatic species in those water bodies. Drastic changes in the conditions of a habitat affect the organisms adversely.

Release of industrial waste into water bodies changes their temperature and chemical composition.  The aquatic species of the water body then find it difficult to adapt to the new changes induced by human activities.

When the water turns warmer the water species have to face difficulties in adjusting to the change. Cold water species will then slowly be replaced by warm water species leading even to extinction of some species.  

Presence of harmful chemicals in the water makes aquatic life difficult in the water bodies.
