Ecosystem is a system formed by the interaction of all living organisms with each other and with the physical elements of the environment. The vulnerability of an ecosystem can be determined through the examination of its location‚ biodiversity‚ extent and linkages. The vulnerability of the ecosystem is closely linked with the effectiveness of the functioning and the diversity of the ecosystem. The resilience of an ecosystem is also important when looking at the survival of ecosystems. Resilience

Activated Sludge Process The activated sludge process is a wastewater treatment method in which the carbonaceous organic matter of wastewater provides an energy source for the production of new cells for a mixed population of microorganisms in an aquatic aerobic environment. The microbes convert carbon into cell tissue and oxidized end products that include carbon dioxide and water. Activated sludge plant involves wastewater aeration in the presence of a microbial suspension‚ solid-liquid separation

Animal Classification 2 Metazoa is another name for Kingdom Animalia. This kingdom does not contain prokaryotes or the potists and all members are multi-cellular and are heterotrophs. They mostly ingest their food and digest it into an internal cavity. Mammals The blue whale is a mammal and lives in the open ocean. They are slate to grayish blue in color. They are mottles with lighter spots on the back and shoulders.

· Taxonomy ○ Science of classification ○ Provides an orderly basis for the naming of organisms and for placing organisms into a category (taxon) ○ Makes use of and makes sense of the fundamental concepts of unity and diversity among living things ○ Basic principle is that members of higher-levels groups share fewer characteristics than those in lower-level groups * Escherichia coli - rod shape and have a Gram-negative cell wall * Even members of the same species display variations

Dissolved Oxygen (DO) 1. What is dissolved oxygen? Dissolved oxygen is the amount of oxygen mixed into the water and is necessary for aquatic life. 2. How does it get into the water? DO gets into the water in many different way but primarily it is absorbed from the atmosphere and aquatic plants. 3. Why is it important? DO is important because it provides oxygen to aquatic organisms and without it they wouldn’t be able to live. Low levels would cause hypoxia and make it extremely difficult for

MICROBES DEPENDENT DENITRIFICATION OF CONTAMINATED WATER INTRODUCTION:- This is an eco-friendly and economical project. In this we want to show how to reduce the harmful effects of nitrogen which gets mixed with water by natural hazard or else by man-made hazards. With the help of two types of bacteria like thiobascillus and rod shaped bacteria of bacillus species‚ we want to reduce the adverse effects of the dissolved nitrogen in the water bodies. HYPOTHESIS:- Nitrate-rich water containing denitrifying
