ecological roles of a caribou in a tundra and the zebras in a savanna how are they similar?

Answer 1

Caribou in the tundra play a crucial role as primary consumers, grazing on lichens and other vegetation, which helps maintain plant community dynamics and provides food for predators. Similarly, zebras in the savanna are also primary consumers, feeding on grasses and influencing the structure of plant communities. Both species serve as prey for larger carnivores, thus contributing to the food web. Additionally, their grazing behaviors can promote nutrient cycling and habitat diversity in their respective ecosystems.
