WebMay 1, 1996 · Insects obtain oxygen from their environments and convey it to cells in many ways, and hence have adapted to nearly all terrestrial and aquatic habitats. The morphological, physiological, and behavioral adaptations of insect respiration must be examined to understand how insects can survive in a wide array of oxygen environments. WebFish and many other aquatic organisms have evolved gills to take up the dissolved oxygen from water ( Figure 20.4 ). Gills are thin tissue filaments that are highly branched and folded. When water passes over the gills, the dissolved oxygen in water rapidly diffuses across the gills into the bloodstream.
