Chapter 29, Problem 1RQ
Summary Introduction
To review:
The fundamental difference between the movement of energy and movement of nutrients through the ecosystem.
Introduction:
Nutrition and energy are necessary to maintain the organisms in the ecosystem and thus, keep the ecosystem functioning. These interactions within biotic communities and their interactions with abiotic factors in the environment determine the movement of nutrients and energy in the ecosystem. Though movements of both the factors are necessary for organisms, there is a fundamental difference between them.
