Question:AHHH im so overwhelmed so here's the deal.... I have a 8 page report due tomoro and i didn't kno about it till today so please help me anything would be GREATLY appreciated! thanks 1. What is a desert biome? 2. What factors contribue the distrubution of desert in the biosphere? 3. What deserts are found in North America 4. How is Sonoran desert different from other deserts in North America? 5. Major plants and animal types found in Sonoran Desert. 6. Describe how each organism is well adapted to survive sonoran desert ***Any help on any question would be terrific!!! Websites that you have for research would also be great!

Question:I need a picture of a food chain of predator-prey examples

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.

Question:for my assignment. Please let it be thorough and make sure it has nearly every animal in the sahara desert. (;

Answers:Well!!!! Sahara Desert is the largest hot desert in the world. It is in North Africa spreading the entire north western region across 9 countries. It is one of the harshest ecosystems on this earth ! The daytime temperature can rise to over 45 degrees Celsius or 113 degrees F. The nights are extremely cold. Strong hot winds blow across the desert carrying sand from one place to another. The dust storms are very common in the hot deserts. They get hardly 10 inches of rain . A typical Sahara desert food chain consists of the date palm (producer) which produces the date fruits. These date fruits when the fall down are eaten by the kangaroo rats ( herbivore ). As the kangroo rat is running away to safety it is caught and eaten by the sandy cat a (carnivore). The sandy cat digests the rat and leaves its droppings in the sand. Soon the decomposers in the sand, the insects, bacteria and worms decompose the droppings and return the nutrients back to the soil for the date palms to absorb and grow. All these animals and plants of the deserts are very well adapted to live successfully in the extreme climatic conditions. Here are few picture:

Question:Okay.. so. I am doing a project for school. I need decomposers, producers, primary consumers, secondary consumers, and tertiary consumers. I already have my decomposers (dung beetle and earth worm) and producers (some plants) and i thought i had all of my primary consumers (rabbits, ground squirrel, other small herbivores) but the things that eat these animals are secondary consumers (kit fox, coyote, etc) and i don't think anything is a natural predator of these types of animals.. can anyone help me with this ? maybe i need to switch some out because i think the coyote and the kit fox are tertiary consumers, and if so, what is the secondary consumers?

Answers:How about the bright red-headed Turkey Vulture. They must find lots there, sometimes seen in large groups flying around. Can you do something with a Desert Lynx?

From Youtube

The Desert Biome :This is my biology project on the Desert Biome. I created a video that includes:food webs, 4 types of deserts with examples, examples of producers, first and secondary consumers and territory consumers. Also, there are charts and graphs showing average temperature and rainfall. This video shows all aspects of the desert biome. As well as was to help save our planet form global warming. - created at animoto.com
