The document discusses the key components of an ecosystem. It defines an ecosystem as a biological community that occurs in some locale, along with the physical and chemical factors that make up its non-living environment. The four main components of an ecosystem are identified as: 1) abiotic substances like carbon dioxide and water; 2) producers like plants that capture energy; 3) consumers like herbivores and carnivores that eat other organisms; and 4) decomposers like fungi and bacteria that break down dead matter and waste. An ecosystem is described as a network of interactions between living organisms and their environment, with energy and nutrients cycling between the different components.
Ecology is the scientific study of organisms `at home' which is called as the `environment'. The term `environment' refers to those parts of the world or the total set of circumstances which surround an organism or a group of organisms.

The project’s aim is to promote the ecological education among school students and local people of Slatsy settlement by attracting them to the territory of the quarry. To make the process both interesting and useful they will be involved into a quest around the territory of the quarry. The main idea is to get people to learn more on biodiversity by playing and by arranging social activity like a photo exhibition, picture contest, designing of the ecology board game. The “Pechurki” quarry is going to be flooded as a part of the recultivation process; we propose to divide the area into two zones, one of which will be unavailable for humans to provide the place for mammals, birds, fish and other species common for the region. The other zone will be a good place to watch the animals from arranged watching stations.
The project won the International contest of the Quarry Life Award 2014 in the category “Biodiversity and Education”

Designing+constructing a geo-ecology and education nature trail at the quarry.
With this trail visitors get an insight of bedrock, soil, terrain shaping, water, climate, vegetation, fauna in correlation between primary origin of the Coastal Mountains (Cordillera+Wrangellia) also as the formation of the inlets and Vancouver Island. Important is an advice+link to the coastal climate+Cold Rain Forest.
The Trail passes geological and ecological spots (such as a few of the bedrock/soil bedding+different rock types) and shows+explains the visitors the realized reconstruction of the rain forest+habitat projects done by the company.
If possible the trail will pass an original part of the Cold Rain Forest to show the nature before the mining started. The trail will be designed after an inspection of the quarry terrain and in cooperation with the Geology Dep. at the University of B.C.,Vancouver. Students will be integrated (course achievement) to design the route and prepare relevant information for visitors.
A container at the entrance of the quarry is used as the starting point and there is a general introduction and safety advice. Visitors get helmet and reflective vests there.
The project won the 1st Prize in National Quarry Life Award in 2014 in North America.

This project seeks to promote edge species which will be used to assess impact on species succession and eventually serve as a means of evaluating and monitoring the success of reclamation.
The focus of this project is on the boundary that lies between the quarry site and the nearby vegetation. Such boundaries are mostly very contrasting in terms of vegetation and the distribution of biodiversity. There is an immediate move from a vegetation zone to a totally degraded area, whereas in nature, mostly there is a gradual change form one habitat to the other. The sudden change in environment limits the movement of organisms as well as discourages species adaptation to degradation hence the drastic effect on species compositions. Our aim is to reduce the contrast between these two environments by looking at the biodiversity in flora and fauna at the quarry site and devising strategies to vegetate the edge and increase biodiversity at the edge.
This project will create a more stable environment for movement of organisms between the two distinct habitats, such as insects which are essential in the process of ecological succession. The vegetated edge will provide bases for the start of ecological succession at the point of reclamation. Selected bio-indicators in various taxanomic groups such as birds, insect and mammals with specialized niches will serve as a tool for measuring the success of reclamation in the future.
The project won the 1st Prize in National Quarry Life Award in 2014 in Indonesia.

Analysis of the makeup of the IBM Twitter Community based on the Twitter relationships and engagement data of 952 accounts relating to existing IBM employees, IBM corporate accounts, IBM alumni and other members of the wider IBM ecosystem.
Zheltokamenka quarry, with an active mining area of 82 hectares, has about 40 hectares of slope surfaces remaining after the extraction of limestone. Actual problem is the lack of suitable technologies for increasing biodiversity in such areas. Our project aims at formation of mobile biodiversity-enriched plant communities that are integrated into appropriate niches on the steep slopes of limestone quarries. Our approach is based on the technology of vertical farming, widely used in architecture. We propose to use microcommunities including rare plant species adapted to the harsh conditions of rocky walls without further support from people. "Green Wall" will consist of communities, planted on the shelves of quarry steep slopes.
This technology will trigger local villagers to perceive ""green walls"" of the quarry as an oasis in the mining lands, and not as destructed space for garbage dumping.
The project won the 1st Prize in National Quarry Life Award in 2014 in Ukraine.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

INTRODUCTION
An ecosystem consists of the biological community that occurs in some
locale, and the physical and chemical factors that make up its non-living or
abiotic environment. There are many examples of ecosystems -- a pond, a
forest, an estuary, a grassland. The boundaries are not fixed in any objective
way, although sometimes they seem obvious, as with the shoreline of a small
pond. Usually the boundaries of an ecosystem are chosen for practical reasons
having to do with the goals of the particular study.
The study of ecosystems mainly consists of the study of certain processes
that link the living, or biotic, components to the non-living, or abiotic,
components. Energy transformations andbiogeochemical cycling are the main
processes that comprise the field of ecosystem ecology. As we learned earlier,
ecology generally is defined as the interactions of organisms with one another
and with the environment in which they occur. We can study ecology at the
level of the individual, the population, the community, and the ecosystem.
Studies of individuals are concerned mostly about physiology, reproduction,
development or behavior, and studies of populations usually focus on the habitat
and resource needs of individual species, their group behaviors, population
growth, and what limits their abundance or causes extinction. Studies
of communities examine how populations of many species interact with one
another, such as predators and their prey, or competitors that share common
needs or resources.
In ecosystem ecology we put all of this together and, insofar as we can,
we try to understand how the system operates as a whole. This means that,
rather than worrying mainly about particular species, we try to focus on major
functional aspects of the system.

COMPONENTS OF AN ECOSYSTEM
1. Abiotic Substances:
These include basic inorganic and organic compounds ofthe environment or
habitat of the organism. The inorganic components of an ecosystem are carbon
dioxide, water, nitrogen, calcium, phosphate, all of which are involved in matter
cycles (biogeochemical cycles).
The organic components of an ecosystemare proteins, carbohydrates,
lipids and amino acids, all of which are synthesized by the biota (flora and
fauna) of an ecosystemand are reached to ecosystem as their wastes, dead
remains, etc, The climate, temperature, light, soil, etc., are other abiotic
components of the ecosystem.
2. Producers:
Producers are autotrophic organisms like chemosynthetic and photosynthetic
bacteria, blue green algae, algae and all other green plants. They are called
ecosystemproducers because they capture energy from non-organic sources,
especially light, and store some of the energy the form of chemical bonds, for
the later use.
Algae of various types are the most important producers of aquatic
ecosystems, although in estuaries and marshes, grasses may be important as
producers. Terrestrial ecosystems have trees, shrubs, herbs, grasses, and mosses
that contribute with varying importance to the production of the ecosystem.
Since heterotrophic organisms depend on plants and other autotrophic
Organisms like bacteria and algae for their nutrition, the amount of energy that
the producers capture, sets the limit on the availability of energy for the
ecosystem. Thus, when a green plant captures a certain amount of energy from
sunlight, it is said to “produce”the energy for the ecosystem.
6. 6
3. Consumers:
They are heterotrophic organisms in the ecosystemwhich eat other living
creatures. There are herbivores, which eat plants, and carnivores, which eat
other animals. They are also called phagotrophs or macroconsumers. Sometimes
herbivores are called primary macroconsumers and carnivores are called
secondaryMacroconsumers.
4. Reducers orDecomposers:
Reducers, decomposers, saprotrophs orMacroconsumers are heterotrophic
organisms that breakdown dead and waste matter. Fungi and certain bacteria are
the prime representatives of this category. Enzymes are secreted by their cells
into or onto dead plant and animal debris. These chemicals digest the dead
organism into smaller bits or molecules, which can be absorbed bythe fungi or
bacteria (saprotrophs).
The decomposers take the energy and matter that they harvest during this
feeding process fortheir own metabolism. Heat is liberated in each chemical
conversion along the metabolic pathway.
No ecosystem could function long without decomposers. Dead organisms
would pile up without rotting, as would waste products. It would not be long
before an essential element, phosphorus, forexample, would be first in short
supply and then gone altogether, because the dead corpses littering the
landscape would be hoarding the entire supply.
Thus, the importance of the decomposers to the ecosystem is that they
tear apart organisms and in their metabolic processes release to the environment
atoms and molecules that can be reused again by autotrophic organisms. They
are not important to the ecosystemfrom the energy point of view but from the
material (nutrient) point of view. Energy cannot be recycled, but matter can be.
Energy must be fed into ecosystem to keep up with the dissipation of heat or the
increase in entropy.

CONCLUSION
An ecosystem is a community of living organisms in conjunction with
the nonliving components of their environment (things like air, water and
mineral soil), interacting as a system. These biotic and abiotic components are
regarded as linked together through nutrient cycles and energy flows. As
ecosystems are defined by the network of interactions among organisms, and
between organisms and their environment, they can be of any size but usually
encompass specific, limited spaces (although some scientists say that the entire
planet is an ecosystem).
Energy, water, nitrogen and soil minerals are other essential abiotic
components of an ecosystem. The energy that flows through ecosystems is
obtained primarily from the sun. It generally enters the system
through photosynthesis, a process that also captures carbon from the
atmosphere. By feeding on plants and on one another, animals play an important
role in the movement of matter and energy through the system. They also
influence the quantity of plant and microbial biomass present. By breaking
down dead organic matter, decomposers release carbon back to the atmosphere
and facilitate nutrient cycling by converting nutrients stored in dead biomass
back to a form that can be readily used by plants and other microbes
