Transcript of Untitled Prezi

desert bobcat Deer A deer is a omnivore because it eats both grass and small animals. Snake A snake is a carnivore because it eats rats . Jack Rabbit A jack rabbit is herbivore because it eats grass and vegetables . The rat is a omnivore because it only eats grains. Grass Rat Cactus Desert hawk A desert hawk is a carnivore because it eats small animals like scorpions . The cactus is a autotroph because it captures energy from the sunlight A grass reproduces on its own. Grass is an example of a producer because it uses energy from the sun to produce food. scorpion Squirrel A scorpion is a carnivore because it eats small other insects so it can have energy . The squirrel is a omnivore because they eat fruits(berries) and insects. P Producers Producers are any kind of green plants such as grass and cactus. They make their own food by taking in sunlight to get energy & to make sugar. If the producers wouldn't exist the secondary, and Tertiary consumers wouldn't have anything to eat because the producers would not produce any food for the herbivores . So if producers wouldnt exist all of the other animals would end up dying since they get no energy . Sources If there was no herbivores then we would be overgrown by plants and the secondary consumer population would go down, because they would have no plants to eat.A secondary consumer is a consumer that eats another consumer for energy .A herbivore is an animal that gets energy from eating plants.Omnivores can also be part of eating plants.Herbivores need alot of energy to stay alive. Herbivores A bobcat
is a carnivore because it eats meat which gives it energy to survive. http://desertcanyonliving.blogspot.com/2011/02/wednesdays-story.html(deer) http://purpleroofs.com/newsletters2008/080109/arizona-sonora-desert-museum.html (bobcat) http://www.californiaherps.com/snakes/snakespics.html (snake) http://www.nps.gov/pais/naturescience/mammals.htm (jackrabbit) http://dwrcdc.nr.utah.gov/rsgis2/search/Display.asp?FlNm=dipodese (rat) http://www.nps.gov/moca/naturescience/grasses.htm (grass) http://www.postcardspinnerrack.com/2012/05/43-saguaro-tree-cactus-unknown-desert.html (cactus) http://www.dreamstime.com/stock-image-desert-hawk-image7077961 (hawk) http://adventure.howstuffworks.com/survival/wilderness/desert-survival5.htm (scorpion) http://jimcloer.blogspot.com/2010_06_01_archive.html (squirrel) Decomposers Decomposers are heterotrophs, and they are organisms that obtain energy by consuming other organisms . If they would get removed from the food web then dead things wouldn't be broken down so then no nutrients will be available for the plants to grow and produce. Carnivores Carnivores generally eat herbivores but can eat omnivores, and sometimes other carnivores. Animals that eat other animals, like carnivores and omnivores are important to any ecosystem, because they keep other species from getting overpopulated. Since carnivores have to hunt down and kill other animals they require a large amount of calories. this means that they have to eat many other animals over the course of they year. The bigger the carnivores are the more the eat. so you should always make sure you have more herbivores and omnivores than carnivores. By Valerie Banuelos , Megan Perez and Gisselle Soto
