Detailed explanation-1: -The rangeland ecosystem is a complex phenomenon involving a multitude of interrelated functions with each influencing the others. The system’s major components are: producers, converters, soils, decomposers and microconsumers, microclimate and manipulators.
Detailed explanation-2: -Pastures are those lands that are primarily used for the production of adapted, domesticated forage plants for livestock. Other grazing lands include woodlands, native pastures, and croplands producing forages.
