The suggested activity below can be adapted according to each class's specific needs. Prior reading of the book "The Adventures of Great Papu" is recommended. In this activity, the teacher can explore ecological concepts such as the different trophic levels that make up the food chain (autotrophs and heterotrophs; producers and consumers) and their interrelations. As a way to promote reflection on the importance of food webs in maintaining species balance and preserving these polar and marine environments, human interference such as tourism, fishing, and scientific research activities could be considered in terms of their impact on ecosystem balance.
