Food+Web

 =__FOOD WEB__ [6] = = = =__**What is a Food Web and how does it work? **__= ==A food web is a web about animals and how they eat.It is also a pattern of food chains that overlap. [1] The food web recognizes that predators may have different types of prey, the diffrent types of prey exist on diferent trophic levels.[2] A tropic level is the energy level of the producers,and consumers. [2] When predators and preys get put together and survive off each other or other animals which makes a food web. Food webs are a lot like food chains which are like ecosystems. A food web starts with sunlight and carbon dioxide. There are many kinds of species in the food web like herbivores, primary carnivores and secondary carnivores. Herbivores include deer,cattle,grasshoppers, termites, Daphnia and anchovies.Primary carnivores include wolves, spiders, warblers and trout. The secondary carnivores include falcons, tuna, and killer whales. Smaller animals then eat leaves and plants are at the bottom of the food web. Unlike the bigger animals that eat the smaller animals are at the top. [3] ==

=__**How are Food Webs and Food Chains different?**__ = = = ==A food chain can look pretty simple, but when you put a bunch of little food chains together they form a food web which can look more complex. If you think about it, how many animals eat grass? Or how many animals eat fish? A food web takes a food chains that have animals that eat grass, fish, and meat and shows the all together. [3] ==

Food Chain Example-Energy Source=Sun>Producer=Tree>Primary Consumer=Deer>Secondary Consumer=Lion>Tertiary Consumer=Vulture. [4]

So in the research that when the fish started to die the animals become more unhabbited becuase we have animals that eat the fish and if the fish were dying the animals that eat the fish would die off as well. So this food web we have made tells you about what animals do when they eat and how the system works. So as you can see we have the leaves had plants at the bottom [<span style="color: rgb(19,23,18);">8] and the bugs next that eat the leaves, then we have animals that would live in a tree that would eat the bugs, also we have the bigger animals that eat the bugs and then we have the biggest off all animals that eat the other smaller animals and that is how a food chain works [<span style="color: rgb(14,17,14);">8] So just like we have the fish that are dying out we have the fish that eat the plants and algea then we go to the animlas that eat the fish and the bigger animals that eat the smaller animals so if we don't have that food web put all together then we will not have have animals becuase they would not be able to eat.

=<span style="color: rgb(0,255,104);">__Why Do We Need Food Webs?__ = ==We Need food webs because if one animal is becoming overpopulated that animal will eventually be so overpopulated that there would be no more resource for that animal to stay alive. So that's why animals need a predator, to keep them from growing at such a fast rate that they eventually disappear. If the Prey starts to die out then so would the predator because they wouldn't be getting what they needed[1]== <span style="color: rgb(36,36,36);"> _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _
