PPT-Aquatic Ecosystems How do we describe aquatic ecosystems?

Aquatic ecosystems are primarily determined by the ecosystems salinity Salinity refers to the dissolved salt content of the water Aquatic ecosystems are divided into freshwater and marine ecosystems. 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. . By Renee Swank. In this activity you will learn all about the types of ecosystem. You can read all of the material and watch a short video on ecosystems. After you have read the material and watched the video, you can take the short quiz to see how much you learned!!. .

One important factor is the chemical balance present in the ecosystem.. Aquatic ecosystems are susceptible to many chemical changes. Usually if the chemistry of a “healthy” ecosystem changes, signs of this change will include sensitive organisms quickly declining in number or disappearing. These types of organisms are called . 4.2 pgs. 94 - 100. Biomes. A large geographical region with a specific range of temperatures and precipitation, and the organisms that are adapted to those conditions of temperature and precipitation. 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. - Jacques Ives Cousteau. 2.
