How might a limited resource, such as food, affect the survival of an individual organism? How might a severe limitation affect the long-term survival of a species?

When food is in limited supply, there will be an increase in competition among individuals of species that consume that food. As the food becomes more limited, the species population will become smaller, since there is not enough food. A severe limitation, for a prolonged time, would likely cause the remaining members to die out of that area, unless the species makes an adaptation that would allow them to survive.
