Most lakes have at least four separate habitats.
The shoreline is full of life, because sunlight reaches the bottom. That helps plants grow. Out near the center, a lake has layers, kind of like a birthday cake. Sunlight reaches the top two layers, which are full of insects, plants, and fish. The bottom layer gets little or no sun. Decomposers wait down there for their next meal. Nutrients are always falling to the floor.
