The spiracles and trachea are structures that enable respiration in insects. Air enters the body through the spiracles and then travels through the trachea. Spiracles are tiny holes in an insect's exoskeleton, and the trachea is a network of tubes.
catches insects and and does respiration.
it gets nutrients from the insects which it could not from the environment.
The structures that enable planarians to expel liquid waste are normally pores. The pores are found on the dorsal surface of the planarians.
ATP
Analogous structures are those that perform similar functions but have different evolutionary origins. A common comparison that illustrates this is the wings of bats and the wings of insects. While both structures enable flight, they are derived from different ancestral origins, highlighting their functional similarity rather than a shared evolutionary path.
Gill
Animals that have gills include fish, some amphibians like tadpoles, and certain invertebrates such as mollusks, crustaceans, and some insects in their larval stages. These gills enable these animals to extract oxygen from water for respiration.
A bullfrog has sacculus that enable it to hear. The sacculus are located behind the eyes of the frog.
