2. Productivity
The nutrient rich (mostly nitrogen and phosphorus) supports many plants and plankton
A lot of oxygen is produced by the plants and used by lake fauna

3. Major Life Forms Phytoplankton Bacteria Aquatic plants
Warm water fish species
In more eutrophic areas: carp
In less eutrophic areas: bass, pike, perch, and panfish

4. Abiotic Limiting Factors
Amount of nutrients in the water (large amounts of nutrients leads to increase in algae population which can lead to an increase in water pH; nutrients in large amounts can also be toxic)
Amount of dissolved oxygen in water (anoxic seasons lead to fishkills, and there will be different species of fish depending on where the oxygen is)
Temperature
Available sunlight

5. Special Features Lakes can become eutrophic from human activity
Frequent toxic blooms

6. Plant Adaptations
Surface plants have bigger leaves to receive sunlight and longer roots to avoid being washed away

7. Animal Adaptations Fish normally need less oxygen
Things to feel through murky water like barbels
