Question
Chapter 29.2, Problem 1CYL
Summary Introduction
To determine:
The trophic levels in a community and give examples of each organisms found in each trophic level.
Introduction:
Ecosystem is composed of all the biotic and abiotic components that exist together and interact with each other for their survival. Ecosystem consists of several trophic levels that mainly include the producers, consumers, detritivores, and decomposers. All the trophic levels in ecosystem are interconnected with each other.
