Grasshoppers and other related arthropods perform their activities with the help of trachea. These are the air filled tubes that are generally open at the surfaces of the thorax along with their abdomen with the help of a pair of spiracles. Spiracles are a kind of valves that allow oxygen to enter and carbon dioxide to escape. They are only used for the purpose of respiration. These tracheoles are found at the end of the tubes i.e. the tracheal tubes. They are insinuated between the cells. They carry the oxygen all through their body.
Now, many of the terrestrial arthropods have evolved a sort of close respiratory system that is only composed of the spiracles, tracheae and the tracheoles. These are present for the purpose of transporting the metabolic gases to and from the various tissues.
Grasshoppers eat leaves and grasses.
from trees just like humans ! ! !
Grasshoppers are consumers because they feed on plants and are considered primary consumers in the food chain. They obtain their energy by consuming other organisms.
Small holes on the bottom of the abdomen (spiracles) lead to tracheal tubes inside the insect. These tubes let air in, which has oxygen in it, to travel straight to the grasshoppers cells.
They eat harvester ants, beetles, and grasshoppers.
Grasshoppers and most insects 'breath' though Spiracles located along the sides of their bodies. These openings feed a net of branching tubes that get oxygen directly into the insects body and tissues.
Our body obtain oxygen to our body by breathing.
In crayfish, gills are required to perform respiration whereas grasshoppers get oxygen for respiration straight from the atmosphere.
Crustaceans obtain oxygen through gills.
The trachea is connected to the air tubes in most grasshoppers. This part of the respiratory system allows grasshoppers to take in oxygen.
Who is "they" ?
you obtain oxygen from your lungs you could breath through your nose and through your mouth
