Answers:One example would be a kangaroo rat that eats a plant seed and gets eaten by a gopher snake that gets eaten by a roadrunner. These animals are found in the Mohave Desert. There are a lot of images at the 2nd link. Hawks, tarantulas, coyotes & bats are other desert predators. The following comes from this link (http://www.desertusa.com/mag05/feb/food.html). A food chain constitutes a complex network of organisms, from plants to animals, through which energy, derived from the sun, flows in the form of organic matter and dissipates in the form of waste heat. The food chain s biological productivity and species diversification depend on factors such as the daily duration and angle of seasonal sunlight, the timely availability of water, the daily swings of seasonal temperatures, the chemical content of the soils, and the availability of nutrients. The food chain complies with two of the most basic notions in biology. First, it has an energy source, in this case, the sun, and an energy sink, in this instance, space. The sun fuels the work required for biologic processes. Space receives the waste heat produced by the work. Otherwise, temperatures would rise to the point that the community of organisms would perish. Second, by definition, a food chain comprises a system of interdependent species. A single isolated species would sooner or later consume the supply of chemicals it needs to live, grow and reproduce. It would perish. Producers and Consumers In a food chain in our Southwestern desert region as in a food chain in any other biologically distinctive region, or biome, on earth it is the plants, or the producers, that capture the energy from the sun and initiate the flow, becoming the first link in the chain. In an almost magical-seeming process called photosynthesis, which means gathering of light, all plants from one-celled diatoms to mesquite and creosote shrubs to the towering saguaro cactus to riverside cottonwoods and willows use the sun s energy, with water and carbon dioxide, to produce a carbohydrate, or sugar, called glucose, a basic component in the food chain. The plants then use the glucose to produce the carbohydrates, proteins and fats required for reproduction and growth, drawing nourishment from various soil nutrients, for instance, nitrogen, phosphorus and potassium. As producers, the plants, in effect, create storehouses of solar energy, setting the dinner table, often impoverished in the desert, for the animals, the consumers. Bumblee, primary consumer that feeds on plant nectar. Plant-eating animals the herbivores, or primary consumers become the second link in the food chain. Flesh-eating animals the carnivores, or secondary and even tertiary consumers become the next links. Plant and flesh eaters the omnivores, like human beings, for example span two or three links. Scavengers, or the detritivores, become the next link in the food chain, and microorganisms, or decomposers, the final consumer link. Decomposers free up nutrients for recycling within the food chain. Ladybird Beetle, secondary consumer that feeds on plant-eating insects such as aphids. In eating plant and/or animal matter, consumers are, in effect, fueling up on stored solar energy, although they surrender the great majority of it as waste heat. At each of the food chain links called trophic levels the consumers give up roughly 90 percent of the energy they ingest. This means that 100 units of plant energy are required to sustain the 10 units of herbivore energy that are required to sustain one unit of carnivore energy. For example, 100 units of grass and shrub energy are required to sustain the 10 units of desert cottontail energy that are required to sustain one unit of red-tailed hawk energy. It also means that the producers the plants constitute 90 percent of all living matter, or biomass, in a biological system such as a food chain, and that the consumers the animals account for only the remaining 10 percent. Plant productivity, always tenuous in our hard and unforgiving deserts, can impose severe limits on the consumer population.
Answers:I would use animals such as a Horned Toad, small insects, and the kangaroo rat at the bottom. Also, some sort of lizard that eats the small insects but is at pretty much the bottom of the chain. Right above those, there would be some sort of snake (eats all four) and the mongoose, which can eat the same as the snake and also the snake. Above there would be a bird of prey (like a red-tailed hawk, depends on the exact place).
Answers:It may be because there are always more prey species than predators, and this is simply a way of representing that. Im not sure exactly what a bald eagle may eat (not native to my country) but I can guarantee that there are many less eagles than their food items (many prey species are needed to sustain the larger predator species. This is replicated in all food chains)
