PPT-Biomes

Chapter 44 Chapter 44 What is a biome Biomes are described in terms of abiotic factors and biotic factors Each biome is associated with seasonal patterns of temperature and precipitation . Vocabulary . Climate zone- an area that has similar average temperature and precipitation throughout. . Equator- an imaginary line that divides Earth into the northern and southern hemispheres. Latitude- a measure of how far north or south a place is from the equator. Climates. Describing Climates. There . are . three. major climate zones:. The planet can be divided into . climate. . zones. , regions that share similar weather conditions.. Tropical Zone. warm temperature which does not vary much throughout the year. 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" (. “Ecology is no. thing”. I. Definition. :. Organisms. Populations. Communities. Ecosystems. II. Levels of Investigations in Ecology. Chpt 52. Chpt 53. Chpt 54. Chpt 55. Distribution of organisms. Importance of Marine Biomes. Oceans represent the largest and most diverse of the . ecosystems.. Salt . water evaporates and turns to rain which falls on the land regions, while most of the oxygen in our atmosphere is generated by algae.  . Biomes. Biomes – . large geographical regions. . that have a . similar climate. and a specific set of biotic and . abiotic. features. Similar ecosystems. . fit into the same biome. Earth has many biomes with recognizable ecosystems – . Tropical rain forest. Tropical. . dry forest. Tropical savanna. Temperate grassland. Desert. Temperate woodland. and shrubland. Temperate forest. Northwestern. coniferous forest. Boreal forest. (Taiga). 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.. 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.. 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.
