We want to know… What a food chain and food web are How energy is transferred from one organism to another within an ecosystemSlide 4: IMPORTANT VOCABULARYSlide 5: POPULATION The number of organisms of the same kind (species) living in a specific place at a specific timeSlide 6: Community Populations of different kinds of organisms that live in the same place at the same timeSlide 7: Species A group of organisms of the same kind that can mate and produce offspring like themselvesSlide 8: Niche The role or job that an organism plays in a habitat How an organism makes a living The place where an animal or plant lives : HABITAT The place where an animal or plant livesSlide 10: Food Chain & Food WebSlide 11: Every organism can be classified as a producer, a consumer or a decomposer depending on its role in the ecosystem LIVING THINGS IN AN ECOSYSTEMSlide 12: An organism that makes its own food through photosynthesis ProducerSlide 13: Examples of producers are plants and algae . Animals that cannot make their own food depend on producers or other consumers for the energy they need to live ProducerSlide 14: Decomposer A living thing that breaks down the remains of dead organismsSlide 15: Decomposer Decomposer get their energy by breaking down or decomposing the remains of dead organism . Examples: Bacteria, fungi (mushroom) and earthwormsBacteria is a microscopic organism that breaks down dead organisms.: Bacteria is a microscopic organism that breaks down dead organisms. BacteriaSlide 17: Decomposer Decomposer also help to recycle nutrients (carbon and nitrogen) in the ecosystemSlide 18: Decomposer Decomposers provide nutrients for plantsSlide 19: Consumer A living thing that obtains energy by eating other living thingsSlide 20: Consumer Consumers cannot make their own food. Most animals are consumers There are three types of consumers: Herbivores, carnivores and omnivoresSlide 21: Question: Is this a producer or a consumer?Slide 22: Herbivore A consumer that eats only plantsSlide 23: Herbivore Herbivores get energy by eating roots, stems, leaves, flowers and fruit Examples: Tiny insects, rabbits, gorillas, deer, snails, caterpillarsSlide 24: carnivore A consumer that eats only other animalsSlide 25: carnivore Carnivores get energy by eating the bodies of other organisms. Not all carnivores eat “meat”, for example, a ladybug eats the entire body of any insect it catches.Slide 26: PREDATOR PREYSlide 27: Predator An animal that hunts down other animalsSlide 28: Prey An animal that is hunted by other animalsSlide 29: Omnivore A consumer that eats both plants and animalsSlide 30: Omnivore Bears are the largest omnivores. They feed fish but also fruits and berries Other examples: cockroaches, crows, raccoons, coyotes, and humansSlide 31: Scavenger A consumer that eats dead animalsVideo: producers, consumers and decomposers: Video: producers, consumers and decomposersSlide 33: All organisms need energy. The main source of energy on earth is sunlight Producers use the energy in sunlight to make their own food How does energy move through an ecosystem?Slide 34: The path of energy transfer in an ecosystem where each member is eaten by another member Food chainSlide 35: FOOD CHAIN Grass Snake Hawk Mushroom PRODUCER PRIMARY CONSUMER SECONDARY CONSUMER DECOMPOSER TERTIARY CONSUMER Dies MouseSlide 36: In this food chain, the grass uses energy from sunlight to produce leaves and fruit The grass gives energy to the mouse The mouse gives energy to the snake The snake gives energy to the hawk When the hawk dies, the mushroom (decomposer) recycles the nutrients and provides them to the plants Food chainSlide 37: Food chain The arrow in a food chain means: “gives energy to.” In a food chain, each organism acts as an energy source for the next organism in the food chainSlide 38: Food web The overlapping food chains that link producers, consumers, and decomposers in an ecosystemSlide 40: Food web A food web gives a real picture of how energy moves through an ecosystem Removing one organism from a food web affects other organismsSlide 41: Food web If a species disappears , the population that depends on it will have a hard time finding food and their population will decreases Any population that the species which disappears feeds on will increase because fewer organisms are eatenVideo: FOOD CHAINS AND WEBS: Video: FOOD CHAINS AND WEBSSlide 43: THE ENERGY PYRAMIDSlide 44: Energy Pyramid An energy pyramid show how much energy is available to each organism at each level of food webSlide 45: Energy Pyramid Some energy is used up by the organisms at each level on the pyramid. As a result, less and less energy is available as you go higher up the energy pyramid Energy pyramids usually have only three or four levels because there is not enough energy to support more.Slide 46: Energy Pyramid Herbivores Carnivores Carnivores and OmnivoresIf all the mice were removed from this simple food chain, the rattlesnakes would most likely — A begin to starve B start eating plants C become producers D increase in number: QUICK QUESTION If all the mice were removed from this simple food chain, the rattlesnakes would most likely — A begin to starve B start eating plants C become producers D increase in number If all the mice were removed from this simple food chain, the rattlesnakes would most likely : If all the mice were removed from this simple food chain, the rattlesnakes would most likely QUICK QUESTION A Begin to starve You do not have the permission to view this presentation.
