Which biotic factor would limit the antelope population in the african savanna?
The correct answer is B) Lion .
In African savana variety of food chains operate. Any food chain consists of producer and different consumers. In a given question antelopes are herbivores. They are the primary consumers and eats green plants (producers). Whereas lions are carnivores. They are predator which kills antelopes and eat them. Therefore, lion will limit the population of antelopes in African savana.
Biotic factors are living components (animals, plants, bacteria, etc...) that either affect the environment or affect population of the ecosystem.
Therefore a biotic factor that would limit the antelope population would be lions.
Hope this helps
