Textbook Problem

As a result of ___, an old animal usually has more pollutants in its body than a young one.

  1. a. bioaccumulation
  2. b. biological magnification

Summary Introduction

Introduction: Mostly the human activities have the potential to not only harm individual species, but also to transform entire biomes. These activities ultimately increase the amount of pollutants in the environment. The main pollutants are various toxic gases such as carbon monoxide, sulfur dioxide, chlorofluorocarbon, and nitrogen oxide. There are some chemical pollutants that became stored in the process of bioaccumulation. There are some pollutants that increase in concentration as they pass up a food chain, by biological magnification.


Reasons for the correct statement:

There are some chemical pollutants that can build up inside an organism’s body. Through the bioaccumulation process, an organism’s tissues store a pollutant that is taken up from the environment, causing the amount in the body to increase over time. In animals, hydrophobic chemical pollutants ingested or absorbed across the skin are accumulated in fatty tissues. The amount of pollutants in an animal’s body increases over time, so long-lived species tend to have a higher amount of fat-soluble pollutants than shorter-lived ones. Therefore, within a species, an old individual has a higher pollutant load than younger ones...
