Chapter 5, Problem 34A

Summary Introduction

Introduction :

Biodiversity is often lost in an environment due to which the abiotic and biotic factors that required a healthy ecosystem are no longer available. Due to certain human activities, such as mining, the land is placed in a state that does not support biodiversity. Biological communities could recover the affected area from natural and man-made disasters. They may require a longer time to recover it if the impact was larger.
