Ecosystems Ppt by Dr. K. M. Ishwar ? An ecosystem is formed by the interactions between all living and non- living things How do living and non- living things interact in an environment? A system resulting from the interaction of all living and non living factors of environment. What is an ecosystem?: What is an ecosystem? System = regularly interacting and interdependent components forming a unified Ecosystem = an ecological system; = a community and its physical environment treated together as a functional system.

Dynamic Ecosystems - Background Information Effects of Canals and Levees on Water Quality Nutrient Enrichment. A major impact on Everglades structure and function has been the delivery of agricultural nutrients. Amount of water Amount of sunlight 3 Type of soil 1 2. ECOSYSTEM : ECOSYSTEM The self- sustaining structural and functional interaction between living and non- living components. OR, MORE SIMPLY: OR, MORE SIMPLY an ecosystem is composed of the organisms and physical environment of a specified area. SIZE: MICRO To MACROAutotrophs: Autotrophs Autotrophs (=self- nourishing) are called primary producers . Photoautotrophs fix energy from the sun and store it in complex organic compounds (= green plants, algae, some bacteria) photoautotroph simple inorganic compounds complex organic compound s light. An ecosystem has abiotic and biotic components: : An ecosystem has abiotic and biotic components: ABIOTIC components : Solar energy provides practically all the energy for ecosystems. Inorganic substances , e. Organic compounds , such as proteins, carbohydrates, lipids, and other complex molecules, form a link between biotic and abiotic components of the system. BIOTIC components: plants ,animals ,micro- orgagisms.: BIOTIC components: plants ,animals ,micro- orgagisms . The biotic components of an ecosystem can be classified according to their mode of energy acquisition . In this type of classification, there are: Autotrophs and Heterotrophs AIR WATER SOIL SUNLIGHT: AIR WATER SOIL SUNLIGHT ABIOTIC COMPONENTSCOMPONENTS OF ECOSYSTEM: COMPONENTS OF ECOSYSTEM Biotic Components- : All living things Producers(plants, animals,& some bacterias ) Consumers ( herbivores, carnivores, omnivores,& scavengers) In addition there is decomposers that help in elements recycling process. Abiotic components: Abiotic components Physical factors - : sunlight,temperature,rainfall,soiltype,water Chemical factors - :nutrients (C,H,N,P,O,S etc.) ,salts,organic substance,toxicants. Power.

Coniferous Forest: Coniferous Forest Grows in places with very cold winters and cool summers. The leaves look like needles so they don. Get less rain than all the other forests. Seed cone. Coastal Forest: Coastal Forest Grows in places where there is lots of rain. Temperature is not too hot or too cold, just cool. Has three layers just like the rain forest: canopy, understory, forest floor. Tropical Rain Forest: Tropical Rain Forest These trees grow in places that are hot and wet all year. Trees are very tall and the leaves are always green. The forest has three layers. Forest floor Understory Canopy. Deciduous Forest : Deciduous Forest Large, flat leaves that drop off in the Fall, new leaves grow in Spring. Leaves change color with the seasons. These trees grow in places that have warm, wet summers and cold winters. Winter. Desert Ecosystem: Desert Ecosystem By Allison Poillot. Climate: Climate The desert is very dry and warm. A very little amount of rain rains a year. Some deserts can be over 1. F. Some deserts are in the Mountains. The Mojave desert is the name of the desert that is located here in California. Desert Animals: Desert Animals Many animals live in the desert. These animals can survive in this hot weather. Let me name some of them. The camel, lizards, rattlesnakes, kangaroo rats, and more! Desert Plants: Desert Plants Now I would like to tell you about the desert plants. These plants can survive in the hot weather because the don. These plants live in the desert. The cactus, saguaro, creosote bushes, and other plants. Desert Ecosystems: Desert Ecosystems LOCATIONDesert . Deserts are dry and hot. There are very few clouds. Two kinds of deserts: Hot deserts Cold deserts Hot deserts Temperatures are very warm all year round The summers are very hot Cold deserts Short, warm summers Long, cold winters Found in places near the north and south poles. Desert Plants: Desert Plants Many plants are found in the desert. They usually grow close to the ground. These plants have special parts that help them save water. The special parts are: thick stem, shallow and wide roots, and thick skin covered with spines instead of leaves. Desert Animals: Desert Animals There are many animals in the desert. They can survive by eating other animals or by eating plants that store water. To protect them from the hot sun, they stay in the shade or in their shelter. Animals may build their shelters inside plants. Some animals sleep during the day and are active at night. Some animals have hard shells to protect them from losing much water. More animals live in hot deserts than in cold deserts. Power. Point Presentation: Roadrunner Anteater Scorpion Gila monster (lizard) Camel.

Point Presentation: Algerian desert part of the Sahara located in Algeria Blue Desert ? Regions with enough average annual precipitation to allow grass to prosper but with precipitation so erratic that drought and fire prevent large stands of trees from growing. Where are Grasslands?: Where are Grasslands? Grasslands can be found on all continents except Antarctica . Three Main Types of Grasslands: Three Main Types of Grasslands Tropical /Temperate /Polar (tundra)Tropical Grasslands: Tropical Grasslands Found in areas with high average temperatures, low to moderate precipitation, and a prolonged dry season. They are widely spread on either side of the equator beyond the borders of tropical rain forests. A type of tropical grassland is a savanna. Savannas: Savannas Have warm temperatures year round, two prolonged dry seasons, and abundant rain the rest of the year. Largest Savannas are found in central and southern Africa, but can also be found in Central South America, Australia, and Southeast Asia. Savanna Species: Savanna Species Common Savanna animal species include wildebeests, gazelles, zebras, giraffes, antelopes, cheetahs, lions, hyenas, eagles, and hawks. Many large Savanna animal species are killed for their economically valuable coats and parts (tigers), tusks (rhinoceroses), and ivory tusks (elephants). Some Savanna plant species include Bermuda grass, candelabra tree, elephant grass, gum tree eucalyptus, whistling thorn, and river bush willow. Temperate Grasslands: Temperate Grassl ands Cover vast expanses of plains and gently rolling hills in the interiors of North and South America, Europe, and Asia. Winters are bitterly cold, summers are hot and dry, and annual precipitation is fairly sparse and falls unevenly through the year. Types of temperate grasslands are the tall- grass prairies and short- grass prairies of the Midwestern and western US and Canada, South American pampas, African veldt, and steppes of central Europe and Asia. Prairie. Prairie Species: Prairie Species Common prairie animal species include the American Bald Eagle, bobcat, bumble bee, coyote, prairie dog, and swift fox. Some prairie plant species include big bluestem grass, blue grama grass, buffalo grass, milkweed, and stinging nettle. Food Web (Prairie): Food Web (Prairie)Symbiotic Relationship: Symbiotic Relationship Certain types of ants and aphids have a relationship known as mutualism, a type of symbiosis, in which species help each other to survive. Aphids, tiny slow- moving insects, live on plants. They feed on nectar, which they suck out of plant stems with their long, pointed mouths. As the aphids digest the nectar, it is formed into a sugary substance called honeydew. The aphids then release honeydew through specialized organs called cornices. Honeydew is one of the ants favorite food. The ants eat as much honeydew as the aphids can produce. The ants treat the aphids like their own private heard. By keeping the aphids close to them at all times, ants have a natural food supply. Abiotic Factors of Grasslands: Abiotic Factors of Grasslands Soil Sunlight Water Rocks Air.
