Ecosystem Ecosystem is consist of Living organisms nonliving things Living organisms interact with Nonliving things. Example of nonliving things: 1- Water. 2 - Soil. 3 - Temperature. 4 -Minerals and Elements. 5 - Air. 6 - Light (Sun). How can Living organisms interact with nonliving things For example (plant)?  Ecosystem The plant use the water, soil, air, light and minerals to make photosynthesis to make own food. - Ecosystem depend on flow of energy between living organisms. - Energy can flow through from : 1- plant to animals. 2- and animals to other animals when they eat each other. 3- when living organisms die, the energy retured to soil. - The sun is the main or primary or initial or original source of energy on the earth. - Ecosystem provides food , water and shelter - Ecosystem are many forms such as ocean, dessert ,rainforest and other.......  Ecosystem Hawks - Hawks eat animals only such as snake, mice, fish. and eat small ground animals. - Hawks don’t eat any plant. - Hawks depend on energy that from plant. - Hawks eat plant indirectly. Q / Which animals can attack the hawks ? eagles or other hawks. When the hawks die , what happen for the energy ? The energy is retured the soil.  Ecosystem What do animals eat ? 1 - Plant absorb the sun to make their own food to grow and gain energy. 2 -Then mice or rabbit eat plant. 3 - Then snake eat rabbit. 4 - Then hawk eats snake 5 - Then the eagle eats hawk or the other hawk eat it 6 - Finally , When the hawk die, the body is composed and return the soil.  Ecosystem flow the energy the sunlight energy plant small animals (mice...) the middle animal (snake...) The large animals (hawks and eagles....) Soil finally  Ecosystem Q / Why animals eat plants or other animals Because they cannot make their own food. There are some activities need more of energy and some activities need less of energy. The examples of activities need more energy : hard work , do exercises The examples of activities need less energy : sleeping, thinking Q / What is the type of energy that help make food ? Sunlight. - sunlight convert (combine) CO2 and water into glucose.  Ecosystem Glucose rich in energy. The type of food that provides them with energy. (Glucose) Plant can only of living organisms make their own food (manufacture) Living organisms can be classified into 3 types by the way of feeding : producers and consumers and decomposers Producers (plants only) - they are organisms make their own food. - can't feed on other plant or other animals. - get the energy from the sun. - produce the glucose rich in energy. - the primary animals eat the plant to get energy.  Ecosystem Consumers (animals) Living organisms eat plant and other animals to get energy Consumers classified into 3 types : 1 - primary Consumers. 2 - secondary Consumers. 3 - tertiary Consumers. Primary Consumers Q / The type of Consumers eat producers to get energy........... The answer is (Primary Consumers) - Primary Consumers have another name is or known as or called as herbivoers  Ecosystem Decomposers (very tiny animals) Living organisms break down the complex dead body into very very small parts Q / which animals can make decomposition? Fungi , bacteria and other tiny animals Q / what happen when decomposition? Small parts that break down rich in nutrients return the soil. Q / Does the nutrients benefit the soil ? Why? Yes , the nutrients increase the fertility of soil for help grow new plant. Dead body of living organism Small parts  Ecosystem Food Chain vs. Food Web Food chains Food web Show how energy pass or flow between living Show serveral organisms or producers to interconnected food consumers to decomposer chains or from plant to animals Many and serveral Few organisms organisms One line, one way complex lines, ways Not better The best 01064139892 1 Miss / Nada soilman  Ecosystem Food Chain vs. Food Web 01064139892 2 Miss / Nada soilman  Ecosystem Food Chain vs. Food Web 01064139892 3 Miss / Nada soilman  Ecosystem The first link in the food chains is Producers. The second link in the food chains is Consumers. The final link in the food chains is Decomposers. The energy from the sun passes to the green plants Some animals may be prey and predator Example : snake eat the frog (the snake is predator ) and the hawk eats the snake (snake is prey) The animal is hunted and eaten be other animal. (prey) The animal hunts and eat other animal. (predator) 01064139892 4 Miss / Nada soilman  Ecosystem Q /It is a better to use a food web instead of food chains ? Because the food web shows many organisms are connected in ecosystem, while a food chain shows a simple relationship between a few organisms. Q / Who can take the sunlight energy directly? The plant only. Q / Why the rest of living organisms are eat plant or animals to obtain the energy ? Because they can’t make their own food, and they can’t get energy directly from the sun. Food chains show relationship of food and energy that passes between living organisms. 01064139892 5 Miss / Nada soilman  Ecosystem 1 - The sun provides energy to producers to make the food 2 - And the plant provides the food to series of consumers. Q / What are the series of consumers? Primary, secondary, and tertiary. Q / Do the series of consumers consist of living organisms eat plant and meat? Yes Food web shows many different organisms share food. Several consumers may eat the same prey. Food web show interactions among many food chains. Humans is a consumer living organisms. 01064139892 6 Miss / Nada soilman
