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

The ultimate source of energy in an ecosystem is either light energy from the sun or chemical energy from compounds originating deep within Earth. Autotrophs (or producers) make their own food using light energy or chemical energy while heterotrophs (or consumers) use other organisms as a source of food. The organisms within an ecosystem are related by their energy roles‚ and an ecosystem can be divided into trophic levels to express these roles

Transport Systems Essay In single celled organisms‚ nutrients‚ water and various substances that are need for basic cellular processes can easily be transported in and out through the cell membrane. This is an effective transport system for microscopic organisms‚ but multicellular organisms require a more complex transport system to sustain itself. Take humans for example; unlike a cell‚ only the outer layer of skin is in contact with the body’s outside environment. It’s not possible for substances

concept of food webs‚ chains and sizes. His organization of species into functional groups; producers‚ consumers‚ decomposers described the characteristic pyramidal shape of food webs‚ with a larger amount of producers (autotrophs) at the bottom and successively smaller amounts of heterotrophs on the following‚ higher levels (Elton C.S.‚ 1926). The Eltonian pyramid of numbers is the basis in describing all food webs. It is based on this pyramid that Raymond L.Linderman published his work upon examining
