Question
Chapter 54.1, Problem 1EQ
Summary Introduction
To determine: The prevailing hypothesis prior to Callaway and Aschehoug’s study stating the reason due to which invasive species succeed in new environments.
Introduction: A system formed with the help of interactions between organisms and their physical environment is known as the ecosystem. The impact of the environment on the distribution of species and the way the organisms are physiologically adapted to their environments is investigated under physiological ecology.
