PPT-Desert and Tundra Biomes

Chapter Seven Most of the year the desert looks lifeless But when rainy season comes the land explodes with life Plants and animals hurry to feed grow and reproduce When the rain is done life seems to disappear again until the next rainy season. 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, . By Jasmine . Brierley. Greenland’s biomes. Biomes in Greenland. A biome is a large, natural . environment that includes . fauna and . flora in it.. There are two biomes in Greenland – Polar Ice Cap and Tundra.. Biomes. Biomes: A large group of ecosystems that share the same type of climax community . A.) Aquatic . Marine or Salt Water:. Photoic. zone- area under that sunlight can pass through. Aphotic zone- area under water that sunlight cannot pass through . Unit Assessment. Third Eight Weeks. Life Science. 1. What is an estuary?. Extremely fertile area where a river meets an ocean; mixture of saltwater and freshwater; serves as a nursery for many species of fish. 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.. 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.. 6.2 – Forest Biomes. 6.3 – Grasslands, Deserts, and . Tundra. Objectives. Describe. . how plants describe the name of a biome.. Explain. . how temperature and precipitation determine which plants grow in an area.. 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. th. Grade Science. Desert. Temperature. Average of 38 degree C during the day. Average of -3.9 degree C during the night. Precipitation. About 250 mm of rain per year. Desert. Vegetation. Cacti, small bushes, short grasses.
