Productivity Very low 50-100 square milligrams per day
Major Life Forms Rainbow trout, golden trout and cutthroat trout are commonly found Algae, Phytoplankton https://www.google.com/url?sa=i&rct=j&q=&esrc=s&source=images&cd=&cad=rja&uact=8&ved=2ahUKEwizn7yE-oDeAhVFy1MKHZ3XBOsQjRx6BAgBEAU&url=http%3A%2F%2Ffisheyeguyphotography.com%2Frainbow-trout-golden-trout-photos%2F&psig=AOvVaw3jKt06cqyWj0_7VFgJcRvN&ust=1539435354714575
Abiotic Limiting Factors The limiting factors are phosphorus, salinity, sunlight, temperature, dissolved oxygen, fertilizers and pollutants.
Special Features Clear Water Excess Oxygen http://mediad.publicbroadcasting.net/p/michigan/files/styles/x_large/public/201710/14946611036_994e33be56_k.jpg
Plant adaptation cold temperatures excess oxygen lack of phosphorus
Animal Adaptations Populations of algae and the animals that feed on them are lower in oligotrophic lakes because of low nutrient concentrations. Lake trout, require cold, well-oxygenated water and primarily live in the hypolimnion of oligotrophic lakes. https://c1.staticflickr.com/9/8300/7949855620_381179252e_b.jpg
