The experiment compares the time spent by larvae near speakers emitting various sounds under current and elevated CO\u2082 conditions. The goal is to identify how increased CO\u2082 levels influence their sound preferences, with the correct conclusion being that elevated CO\u2082 levels disrupt the larvae's attraction to tropical estuarine sounds."}
