In Brazil, biodiversity is extremely rich and varied, housing various animal species. This diversity is composed of both vertebrate animals, which have a backbone, and invertebrates, which mostly do not. These classifications are essential to understand the characteristics and adaptabilities of organisms, as well as to establish conservation strategies for fauna. In a study conducted in the Amazon Rainforest, a group of animals with external skeletons mainly composed of chitin, a rigid substance that provides support and protection, was observed. The presence of this type of exoskeleton is one of the characteristics that allows distinguishing invertebrate animals into specific subgroups. Based on this information and your knowledge of animal classification, identify which group of animals with a chitin exoskeleton was observed in the Amazon Rainforest and explain how this characteristic contributes to the ecological adaptation of these organisms in their environment.
