Chapter 5, Problem 32A

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. Accidental oil spills and harmful chemical spills pollute an environment in such a way that the native organisms could not survive there. Biological communities could recover from natural and man-made disasters. They may require a longer time to recover it if the impact was larger. Ecologists use two approaches for restoring the damaged environment, and they are biological augmentation and bioremediation.

Answer to Problem 32A

Correct answer :

The correct answer is option (A) biological augmentation.

Explanation of Solution

Explanation/justification for the correct answer :

Option (A) biological augmentation. Biological augmentation is one of themethods of ecologists for restoring the damage area. It is the method of adding natural predators to a degraded ecosystem. So, the correct answer is option (A).

Explanation for incorrect answer :

Option (B) biological corridor. Biological corridor is the method of improving the survival of biodiversity by providing corridors, or passageways, between habitat fragments that helps to connect smaller parcels of land and allow organisms to move from one place to another. So, this is an incorrect option.

Option (C) renewable resource. Renewable resources are the resources that are replaced by natural processes faster than they are consumed. Solar energy, agricultural animals, plants, clean air, water etc., are renewable resources. So, this is an incorrect answer.

Option (D) sustainable use. Sustainable use is a use of resources at a rate in which they can be replaced or recycled while preserving the long-term environmental health of the biosphere.So, this is an incorrect answer.
