A population of rabbits on an island at a high population density are beginning to experience a new disease outbreak. What is the effect of the disease on the carrying capacity, and what type of limiting factor is the disease?

1.The disease will cause the carrying capacity to decrease, and the disease is a density independent factor
2.The disease will cause the carrying capacity to increase, and the disease is a density dependent factor
3.The disease will have no effect on the carrying capacity, and the disease is a density independent factor
4.The disease will cause the carrying capacity to lower, and the disease is a density dependent factor
