Transcript of Copy of The Prairie Dog: Food Web and Food Chain Project

Prairie Dog and its EcosystemBy: Julian Lee and Rosa Mazza-Hilway The higher in the food web the more the consumers have to eat to get the same amount of energy as the producer. Only about 10% of the energy is gained.There are multiple ways to get food. You have herbivores that only eat plants and carnivores that only eat meat.Prey are animals hunted for food usually by carnivorous animals. Prairie Dogs are hunted by wolves, badgers, and snakes.First order consumers eat plants to get their energy and then get eaten by bigger animals. Prairie Dogs are considered this.Producers make their own food through photosynthesis and then get eaten by consumers. Prairie grass is a producer.Consumers eat the first order consumers to get their energy and the cycle continues. Wolves, eagles, and badgers are consumers.An ecosystem is formed by the interaction of a community of organisms in their environment.These factors can easily influence each other and are crucial to an ecosystemIn an ecosystem their are both abiotic and biotic factors along with the interactions between these groups. Abiotic- climate, minerals, rocks. Biotic- plants, animals, soil.Food Web of a PrairieMinkPrairie FlowersPrairie GrassPrairie DogBuffaloEagleCoyoteBacteriaThe producers in this food web arethe prairie grass and flowers. They get eaten by the herbivores.In this case, they are the buffalo andprairie dog. Then the carnivores, the eagle and coyote, eat the buffaloes, minkand prairie dogs. The bacteria eats everything, including the plants, after they have died.Some animals are omnivores and they eat plants and animals. Decomposers break down any decaying matter.Food ChainThe difference between afood chain and a food web, is a food chain is a less complexway of showing how energyis passed in an ecosystem.Prairie GrassPrairie DogMinkCoyoteIn this food chain, the prairiedog eats the prairie grass, then the mink eats the prairie dog. The top consumer, the coyote, eats the mink.THE ENDBibliographyhttp://www.defenders.org/prairie-dogs/prairie-dogs-101http://wiki.answers.com/Q/What_is_the_habitat_for_prairie_dogshttp://outdoornebraska.ne.gov/wildlife/programs/projectwild/pdf/PPT_pdfs/Prairies%20&%20Prairie%20Food%20Webs%20PowerPoint.pdfWithout the food web and the food chain, the whole ecosystem would collapse. Energy could not be passed from organism to organism. Food webs and chains areessential to the environment.
