In the fоllоwing sentences, type the missing аccusаtive prepоsition (durch, für, gegen, ohne, um, bis, pro, аnd entlang). Since these are chosen randomly, you may get duplicates, and that's okay.

Costs: flight is energetically expensive, no/little opportunity to feed, physiological demanding (normal weight, gain fat, burn it fast, repeat 2x / year), cross hostile environments (oceans, deserts), many unknowns (predators, food sources, roost sites), unpredictable weather. Which is greater depends on if you migrate or not. If you migrate, the benefits outweigh the costs.
