Summary Introduction

The food chain is the crosslinking process of organisms that consumes other organisms for food and energy flow occurs in a chain reaction. Increase or decrease in a specific population of organism in the food chain leads to an imbalance in ecology. Based on the influence of a particular species in the ecology that species is defined as keystone species. Keystone species concept explains that a specific group of organisms plays a vital role in the ecological niche and its sudden removal disturbs the ecology in a wide spectrum.
