Final answer:
In the African plains, lions depend on zebras for sustenance, while zebras rely on the grasses which they graze, managing the ecosystem. Disturbances can affect this balance, impacting species distribution and abundance. The interdependence of these populations ensures the health and biodiversity of the savanna.
Step-by-step explanation:
The African plains are a dynamic ecosystem where the interdependence of lion, zebra, and grass populations is a classic example of predator-prey relationships and herbivory interacting to form a complex web of life. Lions, as apex predators, rely on herbivores like zebras for food. Zebras, in turn, eat the grasses that flourish on the plains. This interdependence is essential, as lions control the zebra population size, preventing overgrazing. Zebras manage the grasslands by eating the tougher parts of grass, which benefits other herbivores such as wildebeests and contributes to a diverse grassland ecosystem.
Predation is a key ecological interaction where species like lions consume other species, such as zebras. Conversely, zebras are also considered predators in the sense that they consume grass, although they do not kill it. This ongoing cycle of consumption ensures the transfer of energy within the food chain. Any disturbance, like a fire or the introduction of a new predator, can have a ripple effect across the populations, altering the number of species and their distribution on the African plains.
The grass benefits from the grazing of zebras, which can help prevent the spread of fires by keeping grass length short. This grazing pattern creates a mosaic of grass lengths, contributing to the variety found in the large mammal community. Therefore, the balance between lions, zebras, and grass is critical for maintaining the health and biodiversity of African savannas.
