ants

What a nice question? Did not ever think about it. It maybe coz they are very light in weight.

because they are so small and so light and they are made that way lol

Sure, how high, have you seen an ant fall in ravine? Ha ha ha ha ha, just for laughs

Reasons might be..Less weight, so less gravitational force acting upon and bonelessness.

the reason for that is a exoskeleton.. same as if spiders fall from high they aren't going to die..

cause theyre too small to catch weight to crash them :)

because the ants is small like you.... hehehe pls rate me..

An ant doesn't weigh much, that is why there would be lesser impact on the ground once it falls from a high location. Also, an ant is classified as an insect, where these creatures are protected with what is so-called "exoskeletons" - a tough structure covering their body to protect them from the harmful elements of the environment.
