A. Egrets eat insects that are unearthed after livestock graze, but do not affect the livestock

Explanation:

Commensalism is a type of biological interaction where the members of one species obtain a benefit, while members of another species neither benefit nor suffer from the interaction. On the other hand, amensalism is a relationship where one species is harmed while the other remains unaffected. In this example, Egrets are benefited because they obtain insects that can eat, while livestock is unaffected, thereby it is a case of commensalism.

if your boyfriend is cheating on you, my best advice to you is to dump him, he's only going to drag you down. and if you do, don't fret there's plenty better that know how to treat a person right. i mean honestly, the whole point of a romantic relationship is love, and if you love someone you aren't going to cheat on them. i do believe in second chances, but why would he cheat in the first place? i personally feel that if someone cheats, they ruin any chance they wanted/had with you. i wish you the best of luck with this, hang in there.
