In a type III survivorship curve, mortality occurs

  1. Early in life

  2. In the middle age range

  3. Late in life

  4. At a constant rate throughout life

The correct answer is: Early in life

In a type III survivorship curve, mortality occurs early in life. This means that the death rate is highest among young individuals and gradually decreases as they age. This is different from type I and type II curves where mortality is concentrated in later stages of life. Option B and C are incorrect because they do not reflect the distinctive pattern of a type III curve. Option D is also incorrect because it implies a constant death rate, which is not the case for a type III curve. Therefore, option A is the most accurate representation of mortality in a type III survivorship curve.
