Chapter 26, Problem 1MC

Summary Introduction

Introduction:

Behavior can be defined as any visual activity of an organism. The behavior of the organisms depends on the genetic component as well as the environmental factors. The behavior is sometimes influenced by the interactions of the communicator with other organisms. The communication is the central process of learning.

Answer to Problem 1MC

Correct answer:

Defending of a certain specific area by a male lizard can be seen as territoriality. Therefore, option (c) is correct.

Option (c) is given as “territoriality”.

Explanation of Solution

Justify reasons for the correct statement:

The territoriality can be defined as the defense of an area which consists of all the important resources required for the survival of an organism. The establishment over territory takes place through aggressive interactions. Territories are more often defended by male individuals of the species; however, it can be defended by females, families, and mated groups. A male lizard defending a certain area exhibits its territoriality.

Hence, option (c) is correct.

Justify reasons for the incorrect statements:

Option (a) is given as “insight learning”.

There are certain times when the organisms are able to solve a certain problem without getting help from their prior experiences. Such kind of problem-solving behavior is termed as insight learning. This behavior is nowhere concerned with defending a certain area. Hence, it is a wrong answer.

Option (b) is given as “kin selection”.

The kin selection ensures that there is some possibility to contribute genetically to the future progeny by assisting close relatives. Through kin selection, the genetically related individuals are cooperated, which promote their survival. A male lizard defends an area is does not exhibit kin selection. Hence, it is a wrong answer.

Option (d) is given as “altruism”.

The altruism refers to the behavior in which the reproductive success of one individual is kept on stake to benefit other individuals. Defending a certain area is not an altruistic behavior. Hence, it is a wrong answer.

Hence, options (a), (b), and (d) are incorrect.

Conclusion

Territoriality is developed when an organism of a species aggressively interact with other organisms of same species to defend a particular area where all the important resources are available.
