Read the following passage and answer the questions-

The Monarch butterfly, known for its distinct orange and black wings, embarks on one of the most remarkable migrations in the animal kingdom. Each year, millions of these butterflies travel over 3,000 miles from the colder regions of North America to the warmer climates of central Mexico. This incredible journey is not just a feat of endurance but also a vital part of their life cycle.

Monarch butterflies begin their journey in late summer or early fall. Unlike most other insects, they can live up to eight months, allowing them to complete their long migration. The driving force behind this epic journey is the change in weather. As winter approaches, the colder temperatures and scarcity of food sources prompt the butterflies to move to a warmer habitat where they can survive and breed.

Upon reaching their destination in Mexico, Monarchs cluster together on the oyamel fir trees. This clustering is a survival strategy, helping them to stay warm and conserve energy. Throughout the winter, they remain mostly dormant, living off the fat reserves they accumulated during their journey. As winter ends and spring arrives, the butterflies mate. Afterward, they begin their return journey north, where the cycle of life begins anew with their offspring continuing this miraculous migration.

The Monarch butterfly's migration emphasizes the intricate connections within ecosystems and the importance of preserving natural habitats. It serves as a reminder of the delicate balance of nature and the incredible journeys that many creatures endure as part of their survival.
