Sea turtles lay upwards of ~100 eggs in a nest, however of these, it is likely that only one will survive to adulthood. Many hatchlings are consumed by predators before even making it far from their nest. This best describes which type of survivorship curve: Туре I Туре IV Турe II None of these O Type II

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
