Question
Consider the following statements: Pheromones help in 1. communication within species. 2. marking the territory. 3. defence mechanism. Which of the statements given above are correct?
Correct Answer
Option D is the correct answer.
Detailed Explanation
All three statements are correct. Pheromones are chemical signals used for intraspecific communication. They have diverse functions including: communication within species (e.g., alarm pheromones, sex pheromones), marking territory (e.g., in many mammals), and defense (e.g., alarm pheromones that warn conspecifics of danger, or chemical defenses).
Hint
Pheromones serve multiple roles in chemical communication among members of the same species.
