PPT-Land Biomes

Tundra Found in parts of Canada Alaska and Siberia Tundra The Cold Desert Found at latitudes around the North Pole Less than 25 cm 10 precipitation yearly Very cold year round 40ºC 40ºF in winter. 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. . Chapter 10. Objectives. Describe the factors that characterize the various types of aquatic biomes.. 10.1 Aquatic Biomes. Aquatic Biomes. What type of biomes have we learned about so far?. Rainforest, savannah, desert, . 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" (. Pantelleria. .  .                       . Click on the Biomes to learn more!!. Grassland. M. arine. Tundra. Forest. Fresh Water. Desert. Desert Biome. 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.. 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.. An opening in the earth's crust through which molten lava, ash, and gases are ejected. Floodplain. An area of low-lying ground . next to . a river, formed mainly of river sediments and subject to flooding. . 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.. http://www.neok12.com/php/watch.php?v=zX0215667004445d05420545&t=Ecosystems. Why do we find different plants and animals in different biomes?. Plants and animals are adapted to live in their biome. They live within that certain climate.. Dr.E. Introduction . Biomes are the major regional groupings of plants and animals discernible at a global scale. distribution patterns are correlated with regional climate patterns and identified according to the climax vegetation type. History: . Ancient Greeks used to classify the environment into zones which had different degrees of warmth. This resulted in Aristotle describing the terrain in terms of flora and fauna. . Main characteristics and variables used to define biomes is: . 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. 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 Different climates lead to different communities of organisms, especially vegetation.
