Transcript of Abiotic and Biotic Factors

Many plants and animals exist in the desert, contrary to common belief that deserts are empty and sustain little life. Scorpions, coyotes, snakes, spiders, lizard, and cacti are just a few of the biotic factors. One of abiotic factors is the sand. A desert is mainly a lot of sand spanning over vast distances. Sometimes, moss and grass will mix with the sand to create nutrient rich soil. Another abiotic factor is the lack of moisture. Hot and dry deserts yield usually only less than 10 inches or rain per year. Temperature is also an abiotic factor. In most deserts, it is usually hot and dry with temperatures reaching 110 degrees fahrenheit.
Abiotic and Biotic Factors
A desert is a hot area of land that gets very little rain. The desert has an average rainfall of 10 inches. Its climate is 100 degrees Fahrenheit and at night it is 25 degrees Fahrenheit. Deserts generally occur at low latitudes and are close to the equator . Deserts are formed there because the sun hits them directly and constantly.
Organisms that live there
A food web is a a system of interlocking and interdependent food chains. There are many food webs in different biomes. One food web in a desert is when a hawk and kit fox eat a lizard, a lizard eats insects, a kit fox eats a snake, a lizard and a kangaroo rat, a tarantula eats a lizard, and lastly a scorpion eats insects. Hawks and kit foxes are large predators, taratulas, snakes, and scorpions are small predators, carnivores, and insectivores, insects, lizards, and kangaroo rats are plant eaters and primary consumers.
