An Agri-ecosystem is associate degree exceptional living surroundings for wild species of plants (weeds) however conjointly different organisms, like microorganisms, invertebrates and different higher organisms, which all, together with the crop diversity, build up the diverseness of agricultural lands. Diverseness is inextricably coupled with the availability of system services. High diverseness of microorganisms and predatory invertebrates will, for instance, bring positive ends up in the shape of biological gadfly management, organic matter decomposition rate, carbon cycle sweetening, Lately, the intensification of agricultural production, excessive water consumption and environmental pollution (mostly with pesticides and nutrient contamination) caused the loss of plant, invertebrate and vertebrate species on cultivable fields. The most aim of the strategy is to stop any species loss, conservation of their natural habitats and property use of diverseness of species. Plants occupy all-time low level within the biological process chain; so, conservation of their diverseness can enhance species richness of organisms at higher biological process levels.
