How do abiotic factors affect freshwater organisms? pH Photo: M.B. Elder

How do abiotic factors affect freshwater organisms? pH Effects of pH on aquatic life pHEffect All fish, most frogs, insects absent Bacteria die. Detritus accumulates, locking up essential nutrients Optimal for most organisms Rapidly lethal to all species of fish Photo: M.B. Elder

How do abiotic factors affect freshwater organisms? Total Dissolved Solids (TDS) Photo: M.B. Elder

How do abiotic factors affect freshwater organisms? Total Dissolved Solids Natural TDS come from rocks and soil from the watershed that drains into the stream, river, pond or lake. Changes in TDS can indicate a problem. If salts are high, dehydration occurs. Solids cause a laxative effect. Dissolved minerals can affect the pH, raising or lowering depending on the ions present. Range: mg/l Photo: M.B. Elder

How do abiotic factors affect freshwater organisms? Turbidity Photo: M.B. Elder

How do abiotic factors affect freshwater organisms? Turbidity High turbidity decreases sunlight which decreases the rate of photosynthesis. Water that is highly turbid will warm faster, decreasing the dissolved oxygen available for respiration of all organisms. Photo: M.B. Elder

Conclusion: Freshwater organisms-the Biotic part of the Freshwater environment- have “Limits” or “Optimal ranges” in water quality where they prefer to live. The quality of water can be determined by what and how many organisms are living in that environment. Macroinvertebrates are used to evaluate the quality and history of the water environment.
