Transcribed Image Text: American crows (species 1) compete with Turkey Vultures (species 2) for carrion.
Vultures are 4x as large as crows and eat 4x as much. They also can chase Crows
away from carcasses. Therefore, one additional vulture in an area displaces four
crows, but it takes 10 additional crows to displace one vulture. The competition
coefficients are
O alpha12 (imaging the greek alpha with subsript 12) = 10, alpha21 = 4
O alpha12 = 4, alpha21 = 10
O alpha12 = 4, alpha21 = 0.1
O alpha12 0.1, alpha21 = 4
