Organisms and Their Environment. Vocabulary. Ecology. – study of interactions that take place b/t organisms and their environment. Abiotic. factor . – non living parts of an organisms environment (i.e. rocks, air currents). 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. 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 . 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.. Overview: Discovering Ecology. Ecology. is the scientific study of the interactions between organisms and the environment. These interactions determine distribution of organisms and their abundance. 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.. 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.. 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. Biome. a major regional terrestrial community with its own type of climate, vegetation, and animal life. . Q. What determines biomes? . A. Mainly climate. Q. What determines climate?. A. Many things, including tilt of earth’s axis, proximity to oceans, presence of mountains, wind currents. 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
