Role of Temperature on Aquatic Productivity
Posted on : 25 Jan 2020Views: 503
- The water temperature changes less rapidly than the temperature of air because water has a considerably higher specific heat than air, i.e. larger amounts of heat energy must be added to or taken away from water to raise or lower its temperature.
- Since water temperatures are less subject to change, the aquatic organisms have a narrow temperature tolerance limit.
- As a result, even small changes in water temperature are a great threat to the survival of aquatic organisms when compared to the changes in air temperatures in the terrestrial organisms.
- The classification of organisms and limiting factors discussed here apply in general to all aquatic ecosystems - lakes, Ponds, Rivers, Streams, Estuaries, oceans and seas.
