The Singing Bird

This bird lives in the trees outside of my apartment. This biotic factor in the terrestrial ecosystem is a major factor in the food web. The birds are given a place to live by the trees and food by the worms and grub in the ground beneath the trees One difference in an abiotic components between a terrestrial and an aquatic ecosystem is that aquatic ecosystems contain cultural eutrophication and other excess nutrients introduced into its habitat.
