Chapter 55, Problem 2DA
Summary Introduction
To analyze: The reason forthe decrease in the number of ant colonies in the absence of rodents.
Introduction: Food chain can be defined as a representation of the flow of energy in the form of food from one organism to another. Organisms are dependent on another organism for their food. The food chain starts with producers and ends with decomposer.
