Food webs diagram the interaction of multiple food chains within a certain ecosystem, showing the mutual dependency of species and the natural balance of habitats that sustain animal and plant life.
Food webs distinguish levels of producers and consumers by identifying and defining the importance of animal relationships and food sources, beginning with primary producers such as plants, insects and herbivores.
Food webs are important tools in understanding that plants are the foundation of all ecosystems and food chains, sustaining life by providing nourishment and oxygen needed for survival and reproduction.
Food webs aid in the understanding of natural selection, showing the hierarchy of species, with carnivorous, omnivorous and tertiary animals at the top of all food chains.
A food web benefits life science lessons on physical and behavioral adaptations of plants and animals by representing a pattern of consumption based upon natural survival attributes and instincts.
Food webs are helpful in explaining how disruptions in populations due to over-hunting, poaching, global warming and habitat destruction result in food scarcities leading to extinction.
