Organisms are open systems that interact continuously with their environment. The study of the interaction between organisms and the environment; the connectedness between living systems and non-living systems on the Earth is called ecology. The term “ecology” which was coined by Ernst Haeckel comes from the Greek root words oikos logos literally meaning “the study of household”. Haeckel was referring to the interactions within the house of nature and we have used the word ecology (translated from

Urban‚ suburban and agricultural land uses all contribute in some way to lowered water quality. • Uncontrolled human activities on water supply watersheds represent a major source of potential contamination. Efficient and effective water quality protection on both filtered and unfiltered water supplies requires control over human activities. • Watershed cover conditions differ in their regulation of certain nutrients (especially phosphorus

of obsessive compulsive disorders. The most common type is contamination obsession. It is a fear of any disease or contact any subject. As a result of this‚ the person starts to over-clean‚ such as often hand washing. Excessive hand washing can sometimes even lead to a complete deep skin destruction. The person can spend most of their day at home by washing themselves or isolating themselves from being out because of fear of contamination. Another common obsession is ‘’ checking’’. The person may

Tutor: Date: Foundation Engineering Soil exploration obtains information about the subsurface parameters and conditions at the proposed Soil exploration as part of site investigation. In general‚ it deals with determining the suitability of the site for proposed construction. This consists of determining the profile of the soil deposits at and near the site. It mainly consists of taking the soil samples and checking the engineering properties of the soil and testing it in Situ. It then gets to

Bruckner‚ Montana State University‚ Bozeman) Electrical conductivity (EC) which is the ability of a material to transmit (conduct) an electrical current is commonly expressed in units of milliSiemens per meter (mS/m). Soil EC measurements may also be reported in units of deciSiemens per meter (dS/m)‚ which is equal to the reading in mS/m divided by 100. Therefore Soil electrical conductivity (EC) is a property of soil that

Soils of the tropical savannas The soils of the tropical savannas‚ along with the distinctive wet/dry climate‚ are a major determinant of vegetation in the region‚ and of potential land uses. Soil is an outcome of five broad factors: parent material‚ climate‚ relief/slope‚ time and organisms. | Infertile soils Given the variations in all of these in the savannas it is no surprise that there are many different soil types in evidence in northern Australia. Generally speaking the combination of these

between The catena concept The physical and chemical properties of soil can be influenced by its position along a topography. This trend is able to be explained using the catena concept. The topography influences soil formation and its microclimate (Rigg‚ 1993). The different elements of a slope are divided into the ridge‚ crest‚ slope and toeslope (Rigg‚ 1993). The main processes in a catena are the changes in surface runoff‚ soil creep‚ solution and mass movement (Husein‚ et al.‚ 2016).The steep
