Chapter 6, Problem 4STP

Summary Introduction

Introduction:

The need for natural resources to supply the basic needs of the population is growing due to the rise in the human population growth. Developing countries are becoming more developed, and living standards are growing, and the rate of consumption of natural resources is also rising. A long-term strategy for the use and conservation of natural resources is necessary because of the increasing human population growth and an increased rate of natural resource consumption.

Answer to Problem 4STP

Correct answer :

The correct answer is option (C) exponential population growth

Explanation of Solution

Explanation/justification for the correct answer :

Option (C) exponential population growth. Growth in population is an increase in the number of people residing in a given place. When populations expand rapidly, rapid depletion of resources can result in specific environment such as global warming, deforestation and rising biodiversity. So, the correct answer is option (C).

Explanation for incorrect answer :

Option (A) increased competition. Competition is the battle for food, space, and other vital requirements among organisms, both of the same species and of different species. If one species is a stronger competitor, then it will affect the other species by reducing population sizes and/or growth rates. If resources are limitless then there is no competition, and populations will expand exponentially. So, this is an incorrect option.

Option (B) increased emigration. Emigration means movement of the people due to certain difficulties such as due to war, climate, food shortage, etc., which may cause population growth in a specific environment. So, this is an incorrect answer.

Option (D) straight-line population growth. When population increases due to the availability of resources, then straight-line population growth occur. When the resources become scarce, the population growth becomes J shaped curve due to the unavailability of resources. So, this is an incorrect answer.
