Final answer:
The robin and the American elm tree have a mutually beneficial relationship, where the robin finds a safe place to nest and the tree benefits from seed dispersal. This demonstrates the interdependence of species in an ecosystem.
Step-by-step explanation:
The robin and the American elm tree are fatefully linked in their natural habitat. The robin, a bird species commonly found in North America, often builds its nests in the branches of the American elm tree. The tree provides a safe and sturdy location for the robin to lay its eggs and raise its young.
Additionally, the American elm tree provides food for the robin in the form of insects that feed on the tree's leaves and bark. The robin, in turn, helps to disperse the seeds of the American elm tree by consuming the fruit produced by the tree and spreading the seeds through its droppings.
This mutualistic relationship between the robin and the American elm tree demonstrates how different species can depend on each other for survival and reproduction in an ecosystem.
