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
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.
