Chapter 29, Problem 1RQ
Summary Introduction
To determine:
The difference between the movement of energy and the movement of nutrients through the ecosystem.
Introduction:
An ecosystem consists of the two important components that are abiotic and biotic component. The biotic components include all the living organisms present in the environment and the abiotic components include all the nonliving aspects of the environment. Energy and nutrients enter the ecosystem through photosynthesis and pass through an ecosystem from one trophic level to the next. Trophic level represents the category of the organism through which energy passes in the ecosystem
