When does mortality occur in a Type 3 survivorship curve?

Throughout the life span
Early in life
Late in life
At old age

The correct answer is: Early in life

The Type 3 survivorship curve is characterized by high mortality rates early in life, with a strong chance of surviving to adulthood after the critical early years. This means that in this type of curve, mortality occurs early in life at a higher rate compared to the other options. The other options are incorrect because they either state that mortality occurs throughout the life span (option A) or later in life at old age (option D and C). However, in a Type 3 survivorship curve, individuals are more likely to die at a younger age and have a higher chance of surviving to old age. Therefore, option B is the correct answer as it accurately reflects the pattern observed in a Type 3 survivorship curve.
