only work well for the water bodies in the regions in which they were developed‚ and may give anomalous results in other types of water body. Biotic Indices The basis of any aquatic eco-system is water and the quality of the ecosystem may be determined by the quality of the water. Biotic indices can give an indication of the quality of the water. Biotic Indices‚ which are based on the presence or absence of particular indicator groups or species at the sampling point‚ are best suited for waters

Biotic and Abiotic Factors A savanna grassland is an ecological system with scattered shrubs and isolated trees. The grasslands are found on both sides of the equator between tropical rainforests and desert biomes and have warm temperatures year round. A grassland savanna has a variety of biotic and abiotic components ranging from simple to highly specialized plants and animals and physical characteristics. The biotic components of a savanna grassland are the living organisms that inhabit the area

Cabbage tree creek is well looked after by its community‚ and is considered to be very healthy‚ with a high rating for Abiotic and biotic indicators; although it has its a few low quality zones e.g. the waterway under the Park Collins road. Abiotic Abiotic is a scientific term for non living factors that effect the environment. Abiotic and biotic factors combine together to create an eco system. An ecosystem is a community of living and non living things combined together carefully

1 COMPONENTS AND SUBCOMPONENTS OF ENVIRONMENT 1.1 CLASSIFICATION OF ENVIRONMENT The term Environment can be broadly defined as one’s surroundings. To be more specific we can say that it is the physical and biological habitat that surrounds us‚ which can be felt by our physical faculties (seen‚ heard‚ touched‚ smelled and tasted.) The two major classifications of environment are : (A) (B) Physical Environment: External physical factors like Air‚ Water‚ and Land etc. This is also called the Abiotic

Ecosystems Components SCI/256 A region that receives fewer than 10 inches of rain annually is considered a desert. This lack of precipitation loosely illustrates what encompasses the desert ecosystem. Although there are many cold deserts around the globe‚ for the purpose of analysis‚ the focus of this paper will be hot desert ecosystems. The extreme heat of the day in some deserts can reach above 120 degrees and drop down below 32 degrees (National Geographic‚ 1996-2013). These temperature extremes
