The correct Answer is:
### Step-by-Step Solution: 1. **Understanding Migration**: - Migration refers to the movement of organisms from one place to another. For example, if a species originally from location A moves to location B and establishes itself there, this is termed migration. 2. **Analyzing the Statement**: - The statement in question claims that the introduction of new life forms in barren areas is initiated by migration. We need to assess whether this is always true. 3. **Identifying Bare Areas**: - Bare areas are regions that lack vegetation and are often inhospitable for many life forms. They may require specific conditions for new species to thrive. 4. **Role of Pioneer Species**: - When a species migrates to a barren area, it can serve as a pioneer species. Pioneer species are the first organisms to colonize a barren environment, leading to ecological succession. 5. **Evaluating the Statement**: - While migration can lead to the introduction of new life forms, it is not the only way new species can appear in barren areas. Other factors such as seed dispersal by wind, water, or animals, and natural processes like soil formation also play significant roles. 6. **Conclusion**: - Therefore, the statement that the introduction of new life forms in bare areas is initiated solely by the act of migration is not universally true. It can happen through migration, but it is not the only mechanism. Hence, the statement is considered **FALSE**.
