Chapter 54.2, Problem 1C
Summary Introduction
To explain: The way in which dominant and keystone species differ from each other.
Introduction: Explanation and inspection of patterns and processes within a community is known as community ecology. Communities contain large number of individuals of different species those interact with each other and are independent in various ways. Every organism mostly plays one of the three important roles of the ecosystem in community life, namely producer, consumer, or decomposer. There are few species in a community that utilizes strong control of the structure and function of that particular community.
