What kind of competition often leads to extinction because the species that is less well adapted gets fewer of the resources that both species need?
[ "intraspecific competition", "parasitism", "interspecific competition", "mutualism" ]
C
Interspecific competition often leads to extinction. The species that is less well adapted may get fewer of the resources that both species need. As a result, members of that species are less likely to survive, and the species may go extinct.

Explanation: Let the smallest of these number be x. The other two numbers are (x + 2) and (x + 4). x + (x + 2) + (x + 4) = (X + (X+2) + (x+4)) / 3 + 40 3x + 3*(x + 2) + 3*(x + 4) = x + (x + 2) + (x + 4) + 120 9x + 18 = 3x + 126 6x = 108 x = 18 Therefore, the largest number is 22. ANSWER C
