B. The tundra ecosystem, because there is a variety of producers. In the tundra ecosystem, there are multiple types of plants such as moss, grass, and lichen that serve as producers. If one type of grass is attacked or killed by a disease, the other types of producers can still provide food for the herbivores in the ecosystem, helping to sustain the food web.
