I think its because animals can be used to indicate pollution because different animals survive with different levels of oxygen. E.G a sludgeworm or a bloodworm needs little oxygen to suvive so they are indicators of polluted water. Freshwater shrimp and stonfly indicate clean water because they need lots of oxygen to survive. Plants don't use oxygen to survive, they take in carbon dioxide instead.

Which plants and animals are most affected in lakes and rivers?
Water pollution is a serious problem for the entire world. It threatens the health and well being of humans, plants, and animals. As the world became more industrial and smaller due to communications and trade, accidental and purposive hazardous dumping have contributed to the problem of sea pollution. All water pollution is dangerous to the health of living organisms, but sea and river pollution can be especially detrimental to the health of humans and animals. Rivers and seas are used as primary sources of potable water by populations all over the world. Another serious consequence of this pollution is the effect of this pollution on trade in the polluted areas. This paper examines cases which reflect different causes of sea and river pollution, the seriousness of this pollution, the effect of this pollution on trade, and a possible global solution to this problem.
