PPT-Exploring Terrestrial & Aquatic Biomes

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. 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). 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, . Chris Wojan. Background. Logjams increase benthic and emergent aquatic invertebrate abundance and richness through:. Accretion of organic matter. Increased cover. Creation of diverse habitat. Background. “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. . Table of Contents. Section 3: . Aquatic Ecosystems. Section 1: . How Ecosystems Change. Section 2: . Biomes. Chapter: Ecosystems. . Table of Contents. Section 1: . How Ecosystems Change. Mosses from my back yard. 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 . 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. Tropical Rainforest. Tropical Grasslands. Temperate Grasslands. Temperate Deciduous Forest. Desert. Tundra. Taiga. Tropical Rainforest. Characterized by 100 inches of rain a year. Continuous canopy of trees. 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.. 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
