What are the biotic and abiotic factors?
Abiotic And Biotic Factors Of The Desert: Biotic factors are the living beings of an ecosystem that survive. They can refer to the flora, fauna, humans of a place and their interactions. Individuals must have specific physiological behavior and characteristics that allow their survival and reproduction in a defined environment.
The condition of sharing an environment engenders competition between species, given by food, space.
A population is a set of organisms of a species that are in the same area. It refers to living organisms, be single-celled.
The dromedaries have adapted very well to water scarcity. When a thirsty dromedary finds an abundant source of water, he can drink 120 liters in just 10 min.
The deserts undergo great fluctuations of temperatures during a period of 24 hours. Because there is low humidity, deserts do not have insulating protection from moisture and clouds.
The type of soil in an ecosystem ends in which plants can grow, which define which animals will survive. The types of desert soils can vary greatly, but most have a large drain. This means that the floor is loose instead of a compact. When the rain falls in the desert, it quickly seeps into the ground.
Light. Abiotic And Biotic Factors Of The Desert
What are Biotic factors:
Depending on the region: In the desert, only some animals survive the camel (which can lose three-quarters of its weight in water), kangaroo rat, sudo bowl mouse, scorpions, variety of snakes, lizards, hawks, roadrunners, spiders.
As in wildlife, only some plants survive. These they protect themselves from other animals with the thorns they have and with their thick layer of skin, some of them are the cactus, the palm trees, nopales.
It is really amazing that certain plants have learned to survive in the harsh climatic conditions of the deserts.
Most plants need regular rainfall to live. But desert plants have to live without water falling, sometimes for a whole year. In addition, many desert plants have to face extreme temperatures during days of stifling heat and icy nights.
Some desert plants remain hidden in the ground in the form of seeds until the rain falls. Thus they wait for the conditions to be good and do not have to face the harsh desert life.
Desert plants have developed special forms of survival. Thanks to this they can live if they need water to fall regularly.
Some absorb all the water they can during the few times it rains and stores it on their stems or on their leaves.
Some desert trees have several primary roots that grow deep, looking for underground water sources.
Many plants such as creosote, (a kind of shrub), have a vast network of shallow roots to extract every drop of moisture they find under the soil of their desert area. Some desert plants store food and water underground in thick roots, bulbs or tubers.
The stems of these plants are exposed to the sun and wind and may appear dead. But, as soon as it starts raining, they come back to life and give leaves, fruits, and flowers.
To live in the wilderness the animals and plants have had to adapt in different ways to the weather. For example some animals like buzzards, hawks, coyotes, bats, etc. in the day they hide to withstand the sun’s rays and at night they go out to look for food.
In some deserts there are water animals, for example, desert pups or puppies provided that occasional rains are suitable for reproduction.
Prairie dogs, Bats, Quails, Roadrunners, Falcons, Barn Owl, Sparrows, Crows, Coyotes, Buzzards, Bobcats, Tuzas, Kangaroo rats, Spiders, Beetles, Ants, Butterflies, Palomillas, Iguana, Rattlesnake, Chameleons, Turtles, Wild boar, Bura deer, White-tailed deer, Berrendo, Bighorn sheep, Kangaroo rat, Raccoon, Hummingbird, Peregrine falcon, Pupo fish, Desert puppy, Four-horned swordfish.
The diversity of species in the desert depends on several factors such as precipitation and vegetation cover.
