Symbiotic relationship between bird and tree?

Answer 1

It would mostly be commenulism if the bird only nest in it and the tree isn't really bothered or affected by the bird. But it can also be paratism when the bird eats the tree seeds.

Answer 2

A symbiotic relationship between a bird and a tree can take various forms, such as mutualism or commensalism. In mutualism, the bird benefits from the tree by using it for nesting, shelter, or food sources, while the tree benefits from the bird through pollination or seed dispersal. In commensalism, the bird may benefit from the tree without significantly affecting it. These relationships are crucial for the ecosystem as they demonstrate interdependence and the interconnectedness of species in nature.

Answer 3

It depends, of course, on the particular epiphyte and the particular tree. While there is not necessarily any symbiotic relationship between epiphyte and host tree, such relationships are known to exist. For example, many of the species of moss that so often grow thickly on the bark of bigleaf maple (Acer macrophyllum) trees in the Pacific Northwest can fix atmospheric nitrogen; the trees grow aerial roots into the mats of moss that grow upon them and absorb the nitrogen fixed by the moss.

Answer 4

Epiphytes are plants that live perched on sturdier plants. They do not take any nourishment from their host and simply benefit from being better exposed to sunlight.

Some examples:

• many orchids
• many bromeliads (e.g., "Spanish moss" and other members of the pineapple family).

Answer 5

Birds can benefit trees by dispersing seeds through their droppings, which helps in the regeneration of forests. In return, trees provide birds with nesting sites, shelter, and food sources such as fruits and insects. This mutually beneficial relationship helps both species thrive in their ecosystem.
