Answer:
The factor for environmental resistance among the options provided is: high number of predators.
Explanation:
Environmental resistance refers to the factors in an environment that limit the growth, reproduction, and survival of a population. In this case, a high number of predators would increase the pressure on the population, making it more difficult for individuals to survive and reproduce. Therefore, a high number of predators acts as a factor of environmental resistance.
The other options—low rates of disease, favorable habitat availability, and abundance of food—may contribute to the population's ability to survive by reducing factors of environmental resistance.
