Ecosystem is defined as a community which consists of living and non-living organisms living together, intermingling with one another and with the environment and in some way or the other effecting and influencing the life of each other. Ecosystems can be of different varieties,…
Most of the ecosystems are man-made and a very few natural ecosystems are left because of human activities (Schulze & Mooney, 1994).
The structure of an ecosystem consists of two major parts. The first part consists of the biotic components that are the living components of the ecosystem. The second component is the abiotic component which consists of non-living components of the system. A fresh water aquarium is a very good example of ecosystem. The structure of aquarium consists of both biotic and abiotic organisms. Every ecosystem must have a source of energy and the source of energy in an aquarium is usually a tube light or a bulb. This light energy is the source of energy in this case and it provides the required energy to the plants to carry out the process of photosynthesis and produce energy. Fresh water fishes that are present in the aquarium are the consumers and the micro-organisms that are present in the aquarium are the decomposers, they consume the energy as well as decompose the living matter into non-living matter so that the nutrients, minerals and organic matter can be again utilized by the plants. The soil in the aquarium contains the abiotic components like nutrients and minerals and the fresh water also contains different gases which are also the part of abiotic components. The function of the aquarium system is to transfer the energy that is absorbed by the plants to the animals of the ecosystem. This ecosystem also purifies the water and replenishes the environment with the nutrients and minerals. It also provides a habitat to many of the organisms.
By varying any of the organisms or conditions in the aquarium the entire ecosystem can be badly affected. For example if the light in the ecosystem is removed the plants will not be able to carry out the process of photosynthesis and thus will not be able to convert the light energy into an energy that can be consumed by the animals and micro-organisms and ...

While pollution causes illness and death among human beings the loss of biodiversity adversely affects the entire ecosystem. Renewable sources, on the other hand, can reduce environmental pollution to a great extend in comparison with the large scale pollutions from the over use of non-renewable energy sources.
These rocks melt to form molten lava which is spewed out during volcanic eruptions as magma. When magma crystallizes it forms igneous rocks. Igneous rocks on weathering or due to erosion and deposition form sediments. These sediments
ch a study enables me to utilise my nearly two decades of experience at the Social Security Administration and combine that with my ability to obtain feedback from various colleagues throughout the agency in a confidential and non-biased manner (Creswell, 2008). This feedback
Starting off from the 1980s the authors study the rate of biodiversity loss and the effect that it has heard as well as possible further consequences. From the study, some of the resultant aftermaths of the loss of biodiversity include lack of efficiencies by
