what is the significance of biodivercity

"The fundamental property of ecological systems is a certain mixture, or diversity of living things. . ."(1). Biodiversity, or the variety of living things that exist, is fundamental to the existence of life on Earth, and the importance of it cannot be underestimated. In the past few centuries, humans have had an especially negative affect on biodiversity, although, in general, are becoming more aware of its role. However, due to the damage we have caused, and the value that biodiversity has to us as humans, protection of the natural environment is necessary.Biodiversity is an extremely important part of life on Earth. It is not only the variety of living organisms on our planet, but also the interdependence of all these living things, including humans. It thus creates and maintains ecological systems; the most recognizable of which are Earth`s biomes, which can be divided into the broad categories of Forests, Tundra, Aquatic, Grasslands, and Deserts. Life is, in fact, one of the major features that distinguishes biomes from one another. "Biomes are defined as `the world`s major communities, classified according to the predominant vegetation and characterized by adaptations of organisms to that particular environment` (Campbell)."(2). Without vegetation or organisms, these landscapes would be virtually indistinguishable from one another. Clearly life plays a major role in the function of ecosystems, and the variety, or diversity, of this life has played a major role in the evolution of life.First of all question arises what is an ecosystem???Definition of "Ecosystem": An ecosystem is a combination of two words: "ecological" and "system." Together they describe the collection of biotic and abiotic components and processes that comprise and govern the behavior of some defined subset of the biosphere.These are the primary types of ecosystems: natural ecosystems: Natural ecosystems may be terrestrial (meaning desert, forest, or meadow) or aquatic, (pond, river, or lake). A natural ecosystem is a biological environment that is found in nature (e.g. a forest) rather than created or altered by man (a farm).artificial ecosystems: Humans have modified some ecosystems for their own benefit. These are artificial ecosystems. They can be terrestrial (crop fields and gardens) or aquatic (aquariums, dams, and manmade ponds). Hope, the answer will guide you...
