Food Web - National Geographic Society

Oct 19, 2023 · A healthy food web has many autotrophs, many herbivores and few carnivores and omnivores. The biomass of an ecosystem depends on how balanced and connected its food web is. When one part of the food web is threatened, other parts are threatened, too. Then the ecosystem's biomass decreases.
