The ecosystem is a web where all the plants and animals are interconnected with each other and serve each their purpose, and scientists have to consider each ecosystem on a case-by-case basis. The interaction can come in different forms, such as the creatures providing nutrients, getting food, or getting protection from either one. Hummingbirds are keystone species because they help many species of plants reproduce (pollination). >> What did rats evolve from?

The leaves, stem, and its special formation help in nesting requirements of larger birds like hawks and smaller birds like woodpeckers. Since individual observations ranged from one to Its disappearance would mean that the important role it plays, such as pollinating flowers, would no longer be carried out, and a long chain of other organisms would be seriously affected.
