We talk about democracy,
But only when the ruler chooses autocracy.
Don't you see a pattern?
Cause that is what happened,
We only talk,
But that’s where we went wrong.
So let us not talk,
And make a knock,
On the government's door.
And tell them to talk,
On those big tables,
And ask them where did they go wrong?
Or maybe, it was us who went wrong?

ECOSYSTEM IN OUR WORLD
A MAJOR NORM OF NATURE
An ecosystem consists of the biological community that occurs in some local, physical and
chemical factors that make up its non-living or abiotic environment. All living organisms are
a part of an ecosystem.
Ecosystems contain both humans, animals and plants.
Ecosystems are those which sustain both humans and animals, giving them energy, nutrients,
oxygen, water and shelter with other important components.
These don’t have strict boundaries or sizes by as small as a tree or as large as an ocean.
There are many other examples of an ecosystems- a pond, forest or grassland. A study of
ecosystems consists of study of many processes. These processes help to link living or biotic
beings to non-living or non-biotic components.
Some of these processes in ecology are Energy Transformations and Bio-geochemical cycling.
Ecology is generally defined as interactions of organisms with one another.
Ecology is a study of communities which examine how populations of many species interact
with each other such as a predator and prey.
