Discuss the respiratory adaptations of lower animals. How do organisms like insects or aquatic invertebrates efficiently exchange gases with their environment?
Lower animals have various respiratory adaptations. Insects utilize a network of tiny tubes called tracheae to deliver oxygen directly to their tissues. Aquatic invertebrates such as fish and crustaceans rely on gills to extract oxygen from water, utilizing specialized structures to enhance surface area and maximize gas exchange efficiency.
