Textbook Problem

For a given species, the maximum rate of increase per individual under ideal conditions is its _______.

  1. a. biotic potential
  2. b. carrying capacity
  3. c. life history pattern
  4. d. age structure

Summary Introduction

Concept introduction: The number of individuals in a population is termed as population size. Biologists often use the sampling techniques to estimate the population size. It is a current total population of the species within the specified geographical area based on the naturally occurring resources. The rate at which the population size increases is called as growth rate. The growth rate depends on the rate of immigration and births that occur in the population.


Reasons for correct statements:

The growth rate is the rate or speed at which the population size rises. The ideal conditions for surviving of an individual are the availability of resources at optimal conditions that include food, shelter, and other available resources that are unlimited without the predators or pathogens. Factors like age at which the reproduction begins, the duration of the individuals to remain reproductive and the number of offspring they reproduce, can affect the rate of biotic potential.

Option a. is given as “biotic potential”. Biotic potential is the maximum reproducing ability or the highest possible growth of the population. This in turn explains that it has low death rates and highest birth and immigration rates at ideal conditions. Hence, option a. is correct answer.

Reasons for incorrect statements:

Option b. is given as “carrying capacity”...
