What is Freshwater biology?
'''Freshwater biology''' is the study of [[plant]]s and [[animal]]s that live in [[fresh water]]. This includes [[river]]s, [[lake]]s, [[pond]]s, [[marsh]]es and other bodies of water. It is part of the branch of [[science]] called [[Limnology]]. Much freshwater biology takes place in man-made places such as [[sewage treatment]] works and [[water treatment]] works. In these places [[water]] is purified using plants and animals. Keeping them working as hard as possible helps to make the water as cleaner. In recent times freshwater biologists have been looking at how plants and animals change in the autumn and spring. This is helping us to understand more about the effects of [[climate change]]. {{biology-stub}} [[Category:Branches of biology]]
