Bison contribute to the ecosystem by providing habitats for other animals, spreading plant seeds, and enabling other animals to feed in harsh climates. There would be a disbalance in the entire ecosystem as there would be a sudden surge in the prey population which would result in decreasing of food availability of herbivores, thereby causing the decline in the population of the species that are present in the lower trophic levels. A) What are some ways that the blue whale can be helped, include any laws or projects?

What is the effect of any species in a food chain upon one another? American alligators are found in swamps and other subtropical marshy ecosystems. It is also a matter of pride. When they [top predators] are absent from a natural ecosystem when they go extinct the ecological role they fulfill in the ecosystem disappears. Paynes study showed that identifying and protecting keystone species can help preserve the population of many other species. Once jaguars acquire meat for consumption, they use pointy bumps on their tongues, called papillae, to scrape the meat from its bones. c. It can only be a specie. If the algae are left to grow unchecked, the reef would become unhealthy and stop growing.
