Question

1. grasshopper
2.crayfish
what is the class and gaseous exchange of the following organisms

Answer 1

1. Grasshopper

   • Class: Insecta
   • Gaseous Exchange: Grasshoppers exchange gases through a system of tracheae, which are tubes that deliver oxygen directly to tissues and allow carbon dioxide to be removed. Air enters and exits through openings called spiracles located on the sides of the body.

2. Crayfish

   • Class: Malacostraca (which is a class within the subphylum Crustacea)
   • Gaseous Exchange: Crayfish perform gaseous exchange using gills, which are located under the carapace. They extract oxygen from the water and expel carbon dioxide as water flows over the gill surfaces.
