Ecology (from Greek: οἶκος, "house", or "environment"; -λογία, "study of") is the scientific analysis and study of interactions among organisms and their environment. It is an interdisciplinary field that includes biology, geography and Earth science. Ecology includes the study of interactions organisms have with each other, other organisms, and with abiotic components of their environment. Topics of interest to ecologists include the diversity, distribution, amount (biomass), and number (population) of particular organisms, as well as cooperation and competition between organisms, both within and among ecosystems. Ecosystems are composed of dynamically interacting parts including organisms, the communities they make up, and the non-living components of their environment. Ecosystem processes, such as primary production, pedogenesis, nutrient cycling, and various niche construction activities, regulate the flux of energy and matter through an environment. These processes are sustained by organisms with specific life history traits, and the variety of organisms is called biodiversity. Biodiversity, which refers to the varieties of species, genes, and ecosystems, enhances certain ecosystem services.

Ah look at all the lonely people
Ah look at all the lonely people
Eleanor Rigby, picks up the rice
In the church where a wedding has been
Lives in a dream
Waits at the window, wearing the face
That she keeps in a jar by the door
Who is it for
All the lonely people
Where do they all come from?
All the lonely people
Where do they all belong?
Father McKenzie, writing the words
Of a sermon that no one will hear
No one comes near
Look at him working, darning his socks
In the night when there's nobody there
What does he care
All the lonely people
Where do they all come from?
All the lonely people
Where do they all belong?
Ah look at all the lonely people
Ah look at all the lonely people
Eleanor Rigby, died in the church
And was buried along with her name
Nobody came
Father McKenzie, wiping the dirt
From his hands as he walks from the grave
No one was saved
All the lonely people
Where do they all come from?
All the lonely people
Where do they all belong?
