The scope of an ecological cycle covers a wide range of interacting organization levels ranging from the micro-level to the planetary scale phenomena. A given ecological cycle may take thousands of years to mature through and also the area of a given can vary tremendously from a tiny one to a vast one. Ecology is therefore a sub-displine of biology, which is the study of life. The scope of an ecology entails a wide array of interacting levels of organization spanning micro-level i.e. the cells to planetary scale i.e. ecosphere phenomena. Therefore the nature of connection in a given ecological community can’t be explained by knowing the details of each of the species in the isolation since the emergent pattern can neither be revealed nor predicted unless the whole ecosystem is studied entirely. In some instances, however some ecological principles do exhibit collective properties whereas the sum of given components are used to explain the properties as a whole i.e. the birth rates of a given population being equal to the sum of the individual births within a designated time period. The levels of a given biological organization scheme therefore takes the following hierarchical form from the lowest level to the highest level. The Atom- this is the lowest level A molecule- this is defined as a group of atoms Organelle- this is defined as the functional grouping of the biomolecules including the biochemical reactions as well as the reactions. The cell- this is the basic unit of life as well as the grouping of the various organelles The tissue- this is the functional grouping of the various cells The organ-, this is the functional grouping of the various tissues. The organism- this is the basic living system, which is a grouping of the lower-level components which includes at least one cell The population- this is formed from a grouping of organisms of the same species. The community- this is formed from interspecific grouping of the populations The ecosystem- this is defined as grouping of the organisms from all the biological domains in connection to the physical environment The biosphere- this is set of a given set of ecosystems. The energy flow within an ecosystem The energy is defined as the capacity to do work. This is energy usually exist in two forms which include the potential and kinetic. The living things usually use this energy in several forms. This can be radiant or fixed energy. Radiant energy is energy used in the form of heat. On the other hand, fixed energy is the potential chemical energy that is found in many organic substances that can further be broken down to release their energy content. All the energy from the sun that is fixed by the plants during the photosynthesis process performs the following tasks: it can be stored as a chemical energy in the plant or animal materials. Secondly, it ca be passed through the ecosystem along the various food chains. Thirdly, it can escape from the system as an output of the material or heat energy. Whenever there is light, the energy falls on the green plants and a part of it is transformed into chemical energy and thereafter stored in various organic products within the plant. When the herbivorous in turn consume the food, the chemical energy is in turn converted into kinetic energy. In turn the herbivorous are again eaten by the carnivorous of the first order where further energy degradation does occur. Whenever the

Some of the theories base their explanation on physical and social-emotional of people’s earliest years of life. Other theories advance their arguments on effects of environmental influences on families, culture, and community. In addition, other theories focus on learning and thinking process, completion of developmental tasks, and healthiness or ill health shapes people’s behaviour and personality.
Typically, a decision support system will comprise of set of several integrated computer programs to collect, analyze and process information obtained through the daily operations of businesses, and use this information to inform management decisions. There is continuous development of such programs so that businesses can obtain modern, fast and up to date packages for use in their daily operation.
Man requires the resources provided by nature but how will man know how much he is using and how much he is supposed to use for sustainable development? Ecological footprint is the answer to this question as it is a measure of man’s demand for nature and the capability of nature to regenerate what man has used, as well as to absorb the waste produced by man.
The theory of ecological modernization can be defined as a new thought that has a new outlook on the environmental discourse. Therefore it is a new school of thought that has a focus on the issue regarding the environment. At the centre of development of this theory was a social scientific and policy oriented approach in the view of the contemporary society and the environment crisis that the world is facing.
The report aims to bring out the advantages and unique features of the system and to provide a deep analysis on the techniques that were used. The user interface that is designed is explained clearly with the concepts and logistics that were used to design and create it.
Simulation will help management to test their hypothesis and predict possible alternatives. Decision Analysis will help management to analyze and evaluate strategic change and predict possible threats and weaknesses. In accepting change as a constant, marketing management recognizes that customers and consumers change; markets change continuously; and the products and services, the marketing methods, and even the very nature of a company must change to meet them.
Despite in operation since the earliest times, the pace with which human society is growing today was never witnessed in the past. The entire credit for such a rapid pace goes to a number of factors, especially the evolution of science and technology. As a result of the evolution of science and the information communication technology, the way of doing the business has also been changed significantly.
come apparent that every individual needs to exercise responsibility and develop ecological citizenship, or a sense of responsibility towards the preservation of Mother Earth and her resources. The concept of the ecological footprint has been developed in order to attempt to
Ecological perspective is the more individual specific approach in interpreting human behavior, with regard to effects of environmental factors. The factors describing ecological approach include social environment,
This name refers to the headwater of three rivers in Chinese and these are Yangtze River, the Yellow River and the Lancang River. These rivers are the major sources of water in the region whereby Yellow River accounts for 42 per cent of the total volume of water supplied while Yangtze River accounts for 25 % and Lancang River accounts for 15% (Wang, 2008).
