INTRODUCTION: The research topic is based upon the impact of the abiotic factors on community properties in the aquatic ecosystems of bith La Vega and Caroni Swamp. The abiotic factors to be included ate salinity‚ turbidity‚ dissolved oxygen‚ phosphates‚ nitrates‚ pH‚ and temperature. Aqautic abiotic factors have become a prudent issue in these ecosystems affecting the abundance and distribution of species as well as feeding relationships as seen in food webs and food chains. In order to try to solve

It covers a large geographic area and encompasses interacting landscapes. Landscape – is a large land area covering many square kilometers composed of interacting ecosystem. 9 major biomes in the terrestrial biomes 1.

Chapter II Research Body Chalk- is a soft‚ white‚ porous sedimentary rock‚ a form of limestone composed of the mineral calcite. Calcite is calcium carbonate or CaCO3. It forms under reasonably deep marine conditions from the gradual accumulation of minute calcite plates shed from micro-organisms called coccolithophores. It is common to find chert or flint nodules embedded in chalk. Chalk can also refer to other compounds including magnesium silicate and calcium sulfate. Chalk has greater resistance

Summary: Water pollution remains one of the most visible and persistent signs of our impact on the natural world. Cleanup of some older pollutants has been offset by new contaminants that threaten freshwater ecosystems and foul our drinking water. The sight and smell of grossly polluted waterways provided some of the original impetus to the environmental movement in the 1970s. Nearly a century before that‚ the dangers of polluted water to human health drove what became known as the "sanitary

GENERAL INTRODUCTION 1.1 Introduction. ‘’Fish’’ and ‘’Fishes’’ are two terms that usually used in worldwide. However‚ both are referring to different meaning. When referring to individuals of more than one species‚ the term ‘’fishes’’ is properly to used. Besides‚ the term ‘’fish’’ is correctly used when referring to one or more individuals of one species. Hence‚ the term ‘’fish’’ is suitable to be refer to 100 Rainbow Trout‚ while two different trout such as Brook Trout and Brown Trout is correctly
