why might a polluted river contain different plants and animals to a non-polluted river?
Weegy: The more sensative plants and animals would be unable to live in the polluted river. More robust plants and animals might be able to withstand higher levels of pollution so they could live and even be more successful in the polluted river. [ This is because the tougher plants and animals would be able to fill in where the weaker or more sensative plants and animals got killed off. ] (More)

A polluted river might contain different plants and animals to a non-polluted river because of the ecosystem. These changes can lead to the disappearance of sensitive species and the proliferation of pollution-tolerant organisms, resulting in a shift in the composition of plant and animal life.
