From the Paper:

"Delicate balance of species forms all ecosystems on Earth. Equilibrium is attained when a stable relative number of organisms within each species are maintained. This is graphically represented by the food web. This presentation shows the interactions between species in terms of food-base or which species eats which. Inter-species relationship are drawn with arrows until these lines interweave.. In 1966 Robert Paine, an American ecologist, conceived of the idea that not every interaction in the food web is equally important in maintaining the equilibrium of the ecosystem (Keystone Species)."
