Chapter 4, Problem 6A

Summary Introduction

Introduction :

Population growth graph is given with respect to time showing population growth. This graph shows S-shape growth of the population with respect to time. The time period between 1-7, showing no growth in the population with respect to time.

Answer to Problem 6A

Correct answer :

The correct answer is option (d) lag phase.

Explanation of Solution

Explanation/justification for the correct answer :

Option d) lag phase. Lag phase is the initial phase in which no growth in the population occurs with respect to time. So, the correct option is option d).

Explanation for incorrect answer :

Option a) acceleration phase. Acceleration phase means population growth increases with respect to time at a certain pace.

Option b) carrying capacity. Carrying capacity is the maximum number of individuals or the maximum population size which an environment can support at a given time period.

Option c) exponential growth. Exponential growth shows J-shape growth curve , and in this population’s per capita growth remains same regardless of the population size, which results in increase in the population at a faster rate.
