Answer:
In "East and West Fall apart", a religious custom of the Umufiya people is the custom of animal sacrifice. They described sacrificing a rooster before planting crops. The sacrifice was dedicated to Ani, the owner of all the land. The rooster was also dedicated to Ifejioku, the god of yam. This approach is culturally important, because sacrifice is to ensure a good harvest. Ultimately, these sacrifices ensure the health of the village, because if the crop fails, the villagers will lose a large part of their food supply. Since crops are vital to the health of the villagers, sacrifice has great cultural significance.
