Answer:
1) It eliminates extreme traits, 2) represents a population where most individuals are above average
Explanation:
Disruptive selection is DISRUPTIVE to an ecosystem, making the ecosystem scarcer of extreme traits. Also, a BELL-shaped pattern, where a line slopes upward and then back down, would represent a population that is mostly above average, since the climax is a maximum instead of a minimum. Hope that helps :)
