changes in an ecosystem

Many of the worlds habitats and ecosystems depend on a delicate balance of rainfall, temperature and soil type. A complex food chain supply exists based on these factors. Higher temperatures and precipitation changes are likely to cause diverse changes such as increas..

There are saprophytic organisms (mainly bacteria and fungi) that live on dead animals and plants. In terrestrial ecosystem, bacteria act on animal tissue and fungi on plants but there may be exceptions also. This group of organisms plays a vital role in releasing back the biotic componen..

1) Some amount of phosphorus is returned to earth in the form of birds excreta - Guano deposits (excreta of marine birds) and dead fish (around 60,000 tonnes which is less than 0.5% of phosphorus discharged from rivers). 2) Death and decay of organisms and decomposition of organic matter by microo..

o C to 9 o C. The metalimnion or thermocline which has rapid temperature changes between 9 o C to 21 o C. In the terrestrial environment the seasonal and daily fluctuations in temperature are varied and marked. The lowest temperature recorded for any land mass is - 70 o C (Siberia)...

>The food chains and other such interrelationships in the ecosystems create a balance in the environment that is called the ecological balance. However, man tries to modify the environment to suit his needs. This has upset the delicate balance being maintained in the environment. Sustaina..

. For example, more land was converted to cropland in the thirty years since 1950 than had been converted in the whole of the period 1700 to 1850 (The Biodiversity Synthesis Report in the UN Millennium Ecosystem Assessment project). Forty percent of the earth's land surface is now used to..
