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. . Designed by Christopher Becker,. Joeie. Puckett, Michael . Ruthenberg. ,. and . Satura. Thomas. A . Webquest. for 4. th. Grade. Introduction. Biomes are defined as "the world's major communities, classified according to the predominant vegetation and characterized by adaptations of organisms to that particular environment" (. 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!!. Abiotic Elements That Affect Our Water. Water Chemistry. Healthy aquatic ecosystems depend upon many factors. 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.

This biome is the driest; it only receives 50cm of rainfall a year about 10% of the rainfall in the rainforest. Its plants and animals have to survive in an environment with little water and dramatic temperature changes from day to night. Some animals and plants may find if difficult to adapt, but reptiles and cacti thrive in these conditions.. 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.. SIGNIFICANT IDEAS:. Climate determines the type of biome in a given area although individual ecosystems may vary due to many local abiotic and biotic factors.. Succession leads to climax communities that may vary due to random events and interactions over time. This leads to a pattern of alternative stable states for a given ecosystem.. Aquatic ecosystems are primarily determined by the ecosystem’s . salinity. . Salinity refers to the dissolved salt content of the water.. Aquatic ecosystems are divided into freshwater and marine ecosystems.. 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. All seven species in danger through:. Trawler fishing. Destroyed many coral gardens that are turtle feeding grounds. Turtles hunted for leather. Eggs taken for food. Pollution of ocean water. Case Study: The Plight of Sea Turtles. 0 34.7 Current, sunlight, and nutrients are important abiotic factors in freshwater biomes Freshwater biomes cover less than 1% of the Earth, contain less than 0.01% of its water, harbor 6% of all described species, and Section 3: . Aquatic Ecosystems. K. What I Know. W. What I Want to Find Out. L. What I Learned. Essential Questions. What are the major abiotic factors that determine the aquatic ecosystems?. What are transitional aquatic ecosystems and why are they important?.
