Question

A bird building nest on a tree feeds upon the fishes in nearby pond. Whether this bird is part of both i.e. tree as well as pond ecosystem?

Answer 1

The bird is a part of both ecosystems. It builds its nest in a tree for shelter, making the tree part of the terrestrial ecosystem. It also feeds on fish from the pond. As a predator, the bird helps regulate the fish population in the pond and is therefore part of the pond’s (aquatic) ecosystem.
