Desert ecology. Desert ecology is the study of interactions between both biotic and abiotic components of desert environments. A desert ecosystem is defined by interactions between organisms, the climate in which they live, and any other non-living influences on the habitat. Deserts are arid regions that are generally associated with warm ...
Deserts and xeric shrublands are a biome defined by the World Wide Fund for Nature. [ 1 ] Deserts and xeric (Ancient Greek ξηρόςxērós 'dry') shrublands form the largest terrestrial biome, covering 19% of Earth 's land surface area. [ 2 ] Ecoregions in this habitat type vary greatly in the amount of annual rainfall they receive, usually ...
Biome. One way of mapping terrestrial (land) biomes around the world. A biome (/ ˈbaɪ.oʊm /) is a distinct geographical region with specific climate, vegetation, and animal life. It consists of a biological community that has formed in response to its physical environment and regional climate. [1][2] Biomes may span more than one continent.
A desert is a landscape where little precipitation occurs and, consequently, living conditions create unique biomes and ecosystems. The lack of vegetation exposes the unprotected surface of the ground to denudation. About one-third of the land surface of the Earth is arid or semi-arid.
e. An ecosystem (or ecological system) is a system that environments and their organisms form through their interaction. [2]: 458 The biotic and abiotic components are linked together through nutrient cycles and energy flows. Ecosystems are controlled by external and internal factors. External factors such as climate, parent material which ...
Most major kinds of mineral deposits formed by groundwater are located in the deserts. For example, some valuable metallic minerals, such as gold, silver, iron, zinc, and uranium, are found in Western Desert in Australia. This is due to special geological processes, and climate factors in the desert can preserve and enhance mineral deposits. [11]
In ecology, an oasis (/ oʊˈeɪsɪs /; pl.: oases / oʊˈeɪsiːz /) is a fertile area of a desert or semi-desert environment [1] that sustains plant life and provides habitat for animals. Surface water may be present, or water may only be accessible from wells or underground channels created by humans. In geography, an oasis may be a current ...
Setting. The Sahara Desert is the world's largest hot, non-polar desert and is located in North Africa. It extends from the Atlantic Ocean in the west to the Red Sea in the east, and from the Mediterranean Sea in the north to the Sahel savanna in the south. [2] The vast desert encompasses several ecologically distinct regions.
