Question

fix any words that are used incorrectly.
geckos can shed theyre tails to distract predators and escape from danger.

Explanation:

The word "they're" is a contraction of "they are", which is incorrect here. We need the possessive pronoun to show the tails belong to geckos, so "their" is the correct form.

Geckos can shed their tails to distract predators and escape from danger.
