Law of constant proportion: A chemical substance always contains the same elements in a fixed proportion by mass‚ irrespective of the source of compound. Atom: The smallest particle which is the building block of matter. The symbol of the element is made from one or two letters of the English

Introduction This report deals with the study of an ecosystem group and a major functional role within it. The components of the role and other factors such as relationships within the ecosystem are discussed along with quantitative data and examples. The ecosystem group chosen is a local‚ coastal ecosystem called the Barker Inlet – St Kilda Aquatic Reserve and the Torrens Island Conservation Park. Together we have termed them the Barker Inlet Mangrove Ecosystem which is situated approximately

Wastewater Wastewater is any water that has been adversely affected in quality by anthropogenic influence. It comprises liquid waste discharged by domestic residences‚ commercial properties‚ industry‚ and/or agriculture and can encompass a wide range of potential contaminants and concentrations. In the most common usage‚ it refers to the municipal wastewater that contains a broad spectrum of contaminants resulting from the mixing of wastewaters from different sources. Sewage is correctly the

not a part of nor do they fit‚ the Animal‚ Plant‚ or Fungus Kingdom. In the beginning‚ protozoa were placed in a sub-kingdom of Animalia but because of the problems this classification had‚ it later became it ’s own kingdom. All members of this phylum have what are known as nucleated cells and live in aquatic habitats (both freshwater and marine). According to Lynn Margulis‚ K.V. Schwartz and M. Dolan (1994)‚ the cells of all Protoctista originally formed by bacterial symbioses or symbiogenesis
