PPT-Aquatic Biomes Categorized by depth, salinity, temperature, dissolved oxygen

Freshwater streams rivers lakes and wetlands Marine estuaries intertidal zones coral reefs and open oceans Rivers amp Streams Originate from underground springs or as runoff from rain or melting snow. ASHTON CAUDLE, PATRICIA MULLER, SARAH RUTLAND, MATT EVANS, & ROY KIM. BACKGROUND:. Primary productivity is the production of organic compounds from atmospheric or aquatic carbon dioxide mainly through the process of photosynthesis.. Freshwater Biomes. Freshwater is less than 3% of the Hydrosphere. . 90% of the freshwater is locked beneath the Earth’s surface. . Water is cycled through evaporation and transpiration from the atmosphere to the land and back again. . The . study of fresh bodies of water. Lentic. : standing water . (lakes and ponds). Lotic: flowing water . (streams and rivers). Limnology. How might they be different?. Lentic. . vs. Lotic. Glacial erosion and deposition . 70% of the Earth is covered by . o. cean water!. Seawater Composition. Ocean water is made up of three things:. 1.) Dissolved Gases . 2.) Organic Molecules. 3.) Salts. Seawater is a solution.. Solution: Made of a solute and a solvent. . The solubility and saturation value for gases in seawater increase as temperature and salinity decrease and as pressure increases.. 1. . Solubility. is the ability of something to be dissolved and go into solution.. The Aquatic Biome. 3 Basic Areas:. Freshwater. (rivers, lakes). Brackish. Water (estuaries, wetlands). Marine. (oceans, coral reefs). How do ecologist classify?. Salinity. Depth . Whether the water is . Add Name, Date, Block Color in upper right hand corner of . Turbidity. Tab.. Each Tab Should have the following: . Title of Indicator at top of each tab. 1. Turbidity. 2. pH Level. 3. Dissolved Oxygen. Oxygen Measurements. . ( . Winkler’s Method). Factors Affecting Oxygen Levels. 1)Oxygen is removed from the water by chemical reactions, the decay process and respiration.. 2)Water temperature and atmospheric . . of . seawater . and sound speed in seawater. Know a typical value for sound speed in the ocean. Discuss the loss of acoustic . intensity (. attenuation) due to spreading (cylindrical and spherical), absorption, and scattering.. 97% oceans. 2% glaciers. 1% lakes, rivers, streams. Precipitation. over land. Transport. over land. Solar energy. Net movement of. water vapor by wind. Evaporation. from ocean. Percolation. through. soil. Explain how biomes are characterized. Describe how net primary production varies among biomes. Explain how organisms are adapted to the conditions of their biomes. Describe the criteria ecologist use to classify aquatic systems. CHAPTER. Too Much of a Good Thing?. Elephant populations in southern Africa declined sharply due to hunting but have made overwhelming comebacks within nature reserves and parks.. Some worry that elephant overpopulation is causing a decline in local biodiversity and damage to farms and infrastructure.. How are physical and biological factors used to determine water quality?. How do we know if water is safe to drink?. How do we know if water is safe for aquatic organisms?. Water Quality Indicators. Temperature. A BIG group of LIVING things . Different kinds of species. Large geographical area/ REGION. How are biomes commonly identified?. Biomes are commonly identified by the Biome’s dominant . plant species.
