With behavioral plasticity, behavior varies depending on ________.

  1. a. the time of day
  2. b. an individual’s age
  3. c. environmental factors
  4. d. an individual’s genotype

Summary Introduction

Concept introduction: Behavior is the capacity of an animal to learn through experience. Behavioral ecology is the study of how natural selection shapes the behavior of an organism. Phenotypic plasticity refers to the ability of an individual with specific genotypes, which express different phenotypes in different environments.

Explanation

Reasons for the correct statement:

There are several factors that affects the behavior that include proximate and ultimate causes of behavior, genetic variation within a species, genetic difference between the species and environmental effects.

Option c. is given as “environmental factors”. Organisms show behavioral plasticity if their behavioral traits are affected by environmental factors. Behavioral plasticity is the behavioral phenotype associated with a genotype, which depends on the conditions in the animals' environment. Hence, option c. is correct answer.

Reasons for the incorrect statements:

Option a. is given as “the time of day”. If the behavior changes occur depending on the time of day, then it is called Photoperiodism, not a behavioral plasticity...
