Lakes and Rivers
Though fresh water comprises only three percent of all the water in the world, it is what makes life on the land possible. Readers will discover the diverse world of lakes and rivers and explore how the simplest forms of life such as light-trapping plankton pass on energy to more complex forms of life such as tadpoles and fish. Author Philip Johansson shows how all living things, from algae to river otters, are connected in this freshwater biome.

Readers join Dr. David Harper and his team, searching for crayfish from Louisiana that were introduced into a Kenyan lake. Brought with the intent of helping the people of the area with food production, the crayfish have reproduced and eaten up most of the kinds of plants that once formed the base of the food web in Lake Naivasha. Now the group is trying to find out how the introduction of a foreign species has changed the food web there in Africa, and how it can be restored.
