The biotic factors that affect deserts include all of the live organisms in the environment, while the abiotic factors comprise all of the desert’s non-living components. Plants such as drought-resistant grasses, cacti, aloe plants, and other succulents are common biotic elements in deserts, whereas the soil, rocks, minerals, and sands that make up the substrate are common abiotic components.
Despite their arid and harsh aspect, deserts are generally alive. Coyotes, lizards, snakes, rodents, turtles, and birds are examples of animals that play a significant biotic role in desert ecosystems. Insects, spiders, scorpions, flies, beetles, and centipedes are among the smaller species that live in deserts.
Microorganisms and single-celled organisms play an essential role in desert ecosystems. Bacteria, lichens, and amoebas all seek for damp environments in which to thrive. Some deserts, such as the Antarctic desert, are completely devoid of life.
Desert ecosystems are also influenced by the harsh sunlight and winds. While deserts aren’t known for having a lot of standing water, it is present and plays a crucial role in the ecosystem. While rain is infrequent, water is frequently collected in succulent plants and accumulates under covered areas.
