A grasshopper respires by means of its

Explanation

A grasshopper is an insect that needs oxygen to survive. Respiration is the process by which living organisms obtain oxygen and release carbon dioxide. The question is asking how a grasshopper breathes, specifically, what organ or structure it uses to respire. The options provided are lung-books, gills, lungs, and tracheal tubes. Lung-books and gills are not correct because these organs are not found in grasshoppers. Lungs are also not correct because grasshoppers do not have lungs like mammals do. The correct answer is tracheal tubes. Tracheal tubes are a network of tubes that run throughout the body of an insect and allow oxygen to diffuse directly into the cells. These tubes are like a series of tiny straws that allow air to enter the body and reach the tissues. Insects have a system of valves and spiracles (tiny openings) that regulate the flow of air in and out of the tracheal tubes. In summary, grasshoppers respire by using tracheal tubes. These tubes are a network of tiny tubes that allow oxygen to enter the body and reach the cells. They are not lungs or gills.
