The migration of animals can affect ecosystems in several ways. When animals migrate, they can transport seeds, nutrients, and energy from one area to another, which can influence the distribution of plants and other species in the ecosystem. Additionally, the movement of animals can help in the pollination of plants, dispersal of seeds, and regulation of prey populations. Migration can also impact the food web and energy flow within ecosystems. Overall, animal migration plays a crucial role in maintaining the balance and biodiversity of ecosystems.
