Freshwater Ecosystems Rivers, ponds, lakes and streams have fresh water. Lakes and rivers are closely tied. Some lakes are the source for some rivers. Important rivers, most often, originate from lakes. Some rivers end in lakes. Since both rivers and lakes are freshwater and flow in and out of each other, they share similar characteristics and many species reside in both habitats.

Deciduous Forest What's A Temperate Deciduous Forest Like? One of the most interesting features of the temperate deciduous forest is its changing seasons. The word "deciduous" means exactly what the leaves on these trees do: change color in autumn, fall off in the winter, and grow back again in the spring. This adaptation helps trees in the forest survive winter.
