Question : I need to know the carnivore that is at the top of the food chain is.
Answer : It depends on what part of the sahara you are in. Could be crocs, insects, snakes, sand cats, hyena, jackal, baboon...
Like I said it depends on what part of the desert you are in.
Question : 1. What are the differences between food chains and food webs and food pyramids (energy pyramids)?
2. How is a food web more sophisticated than a food chain? What is the purpose of the food pyramid?
3. Contrast the movement of energy and matter through the ecosystem.
Does anyone know what kinds of animals would be on the fifth trophic level?
Answer : 1. Food chains show the transfer of energy from one organism to another organism(leaf gets eaten bug bug which gets eaten by bird). Food webs show the transfer of energy between one organism and multiple other organisms(bird eats bugs and seeds and is eaten by fox and hawk). Food pyramids show the different trophic levels in an ecosystem and the transfer of energy from one level to the next (show decrease of energy in higher trophic levels).
2. A food web shows more relationships then a food chain. It's basically food chains put together. An energy pyramid shows the transfer and decrease of energy in trophic levels.
A killer whale could be at the fifth trophic level and so could a hawk. Basically top carnivores.
Question : I can not find anything about their food chain in there ecosystem. All I know is that the American Alligator is at the top. If you know anything else or what that food chain is please answer this question.
Answer : Alligators will eat pretty much anything they can find, this includes birds, fish, reptiles (mostly turtles), small to medium sized mammals and invertabres.
You could have; plant matter - mosquito - leopard frog - heron or small mammal ( example: Blue Heron, raccoon) - alligator
