Ecosystem and Food Web
Acknowledgement
First of all I’m very thankful to Tr.Sudharshan for assigning us this project because in previous years and class we were just well known about the term “ecosystem” but now as we have done this project we have now learned various things about ecosystem in depth and that will help us in our course study in coming days. This project is based on term “ecosystem” and “Food chain” after going through it many will be able to answer these questions:

* What is an ecosystem, and how can we study one? * Is the earth an open or closed system with respect to energy and elements? * Tropic level * What are the types of food chain * Food web.etc

Content 1. Introduction on ecosystem 2. Components of ecosystem 3. Trophic level 4. Food chain (introduction) 5. Type of food chain 6. Food web 7. Conclusion

INTRODUCTION ON ECOSYSTEM An ecosystem is a community of living organisms (plants and animals) sharing an environment. The largest ecosystems are called biomes.
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, 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 and biogeochemical 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.

    An ecosystem is a community of living organisms joined with the non-living components of their environment interacting as a system. Mangroves, Rocky Shores and Sand Dunes may be seen as three independent parts of the ecosystem but if one is disturbed then it affects the other parts of the cycle. There are many examples of ecosystems such as a pond, forest, an estuary, grassland and many more. Hastings Point is an estuary that is continuously threatened by development.…

    An ecosystem is composed of the producers, consumers, decomposers and the living organism that interact and reside in this habitat. They are part of the food web and their roles are important in maintaining the environment. Producers make food, the consumers feed on it but at the same time the decomposers also break down the food to go back to the food web. Mother Nature has assigned different roles (plants and animals) that will sustain our environment and as caretakers we must preserve the ecosystem (no land clearing) so that it will continue to thrive and…

    As stated above, an ecosystem is a place where biotic and abiotic components interact within their environment. Living parts of an ecosystem include animals and plants. These animals and plants perform roles of producers, consumers, or decomposers. According to Raven & Berg (2004), these three roles are indispensable within ecosystems. Producers provide food and oxygen, consumers create balance between producers and decomposers, and decomposers prevent accumulation of dead organisms and waste products (p. 72). Non-living components of ecosystems include soil, sun, and weather conditions. Working together, the biotic and abiotic components cycle nutrients within the ecosystem. This is vital action because without nutrients the ecosystem and its inhabitants would not survive. Where do ecosystems come from and how do they begin? The answer lies in the definition of primary succession.…

    Ecology - is the scientific study of interactions among organisms and their environment, organisms have with each other, and with their abiotic environment. Topics of interest to ecologists include the diversity, distribution, amount (biomass), number (population) of organisms, as well as competition between them within and among ecosystems. Ecosystems are composed of dynamically interacting parts including organisms, the communities they make up, and the non-living components of their environment. Ecosystem processes, such asprimary production, pedogenesis, nutrient cycling, and various niche constructionactivities, regulate the flux of energy and matter through an environment. These processes are sustained by organisms with specific life history traits, and the variety of organisms is called biodiversity. Biodiversity, which refers to the varieties of species,genes, and ecosystems, enhances certain ecosystem services.…
