Snake (D) Hawk (D) Coyote (D)
Insects (C) Scorpion (C) Lizard (C) Quail (C) Mouse (C)
Cactus (P) Grass (P) When you are explaining an ecosystem you have producers, consumers, and decomposers. Producers are the plants and the tress in the ecosystem that provide the energy to the ecosystem. As for the desert the producers are cactus and grass. The consumers of the ecosystem are in three different kinds, they are herbivores, carnivores, and omnivores. Herbivores are the consumers that eat plants which in the ecosystem that I chose are jackrabbits, mice, quail, and insects. The carnivores eat meat. The carnivores in my ecosystem are scorpions, snakes, and lizards. Omnivores eat both plants and animals. I do not have any of those in my food web. Then you have decomposers, which feed off of dead organisms. In my ecosystem that I chose, that would be hawks and coyotes. This is what is called the cycle of life within the desert ecosystem. When you talk about the problems that humans cause on any ecosystem, it would be the growth in the population. Every time we expand where we as humans live we move into their territory which changes the food web in a very drastic way.
When we talk about the abiotic factor within my ecosystem you are talking about rocks, dirt, sun, wind, rain, and extreme temperatures. In my ecosystem you have cactus and grass which gets ate by mice, jackrabbits, insects, and quail, which get eaten by scorpions, lizards, and snakes, which get eaten by hawks and coyotes. Cactus are a plant that has learned to survive in the extreme weather by being able to hold on to the water within itself to survive the extreme heat and dryness during the summer.
