Chapter 54, Problem 13TYU
Summary Introduction
To explain: Whether humans are dominant species or key stone species.
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.
