majestic creatures — the polar bear. From its brown bear ancestry‚ the predator evolved to be a master of a harsh and unwelcoming ice kingdom. Intelligent‚ adaptable and fierce‚ the polar bear learned how to survive in a place that offers few comforts to any creature. But now that very environment is in flux.

WHAT IS ECOSYSTEM 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 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 ecosystem components are the two main topics

But all of these elements do not exist just to be there‚ they have a further important meaning interacting with organisms. We are talking about a biological community of interacting organisms and their physical

For their habitat‚ they are the non-living nature which are soil‚ sunlight‚ water‚ precipitation. There are two types of ecosystem.

An ecosystem is a community of living organisms (plants‚ animals and microbes) in conjunction with the nonliving components of their environment (things like air‚ water and mineral soil)‚ interacting as a system. These 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 come in any size but usually encompass specific‚ limited spaces (although
