protection. The term "ecosystem" refers to a community of plants and animals that share a common space and common resources‚ and are all dependent on one another for survival. Ecosystems are characterised by the complex interactions between these abiotic and biotic environments which involves a number of major systems such as the biosphere‚ the lithosphere‚ the hydrosphere and the atmosphere. Ecosystems are delicately balanced. If one component fails to thrive‚ the others become weakened‚ and may fail

quickly lost‚ creating the extreme cold nights. Because of the temperature swings and arid environment‚ both plants and animals have evolved adaptations to thrive in the harsh conditions (Encyclopedia of Earth‚ 2010-2011). Within desert biomes‚ biotic life adapts characteristics‚ which are advantageous to extreme temperature and precipitation conditions of their ecosystem. Indigenous vegetation and organisms have adapted many survival techniques through natural selection. One example of this can

Ecology EQ’s 2. Abiotic and biotic components influence each other. For instance‚ temperature (abiotic factor) can make plants (biotic factor) reproduce more or reproduce less. Also water‚ an abiotic factor‚ has an effect on how animals‚ a biotic factor‚ survive in certain areas of the world. 3. Because a different niche allows multiple species of organisms to coexist. If all organisms had the same niche‚ then there would be heavy competition for food‚ shelter‚ etc. Having different niches gives
