Excretion
"Carbon dioxide diffuses from the grasshopper's
body fluids into tracheal tubes and is expelled through the small openings called spiracles.
- MALPIGHIAN
TUBULES are the excretory organs.
- minerals and uric acid are expelled
with fecal matter.(BIRDS and REPTILES do the same thing that insects do.) It is the uric
acid in the fecal matter of birds that makes it necessary to wipe this substance off your car or the paint will be ruined.
- the excretion of uric acid
is a water-conserving mechanism of particular advantage to an egg-laying terrestrial organism.
- of all the nitrogenous wastes, ammonia (NH3), is the most toxic, uric acid is the least toxic.
- all insects secrete uric acid.
. If you hold a grasshopper, you can oftensee
its abdomen compressing in and expanding out. This movement evensuggests breathing. The openings are the beginning of tubes
that runthroughout the body cavity to provide oxygen and remove carbon dioxide.Actually the blood of the locust just moves
freely around the body for themost part and oxygen / carbon dioxide diffusion is not as efficient as theclosed circulatory
system of the bigger animals like ourselves."
Locusts are grasshoppers for the most part and they breathe through openingsthat line the sides of the abdomen. If you

Compare & Contrast
Grasshoppers are similar
to humans because we both reproduce, eat, sleep, digest, and are living things.
We differ because we eat
different foods, live in different environments, and are 2 different organisms.
How do the differences benefit to the organism in its environment?
One benifit that grasshoppers have from
living in an environment thats different from humans is that they have all the food source they require in their environment.
The benefit that humans have from eating foods that are different from the foods that grasshoppers eat is that the food that
humans eat are probably much healthier than the food grasshoppers eat.
