In an area, a population with large size individuals having long life span, more parental care and slow development was present. The type of population growth curve will be J-shaped, Z-shaped, or S-shaped?

In the given condition, the type of population growth curve will be S-shaped which is called a sigmoid curve. This type of growth curve represents that on introduction to a new area, the population grows slowly in the beginning followed by a sharp exponential increase in the growth rate. This is further followed by the stationary growth phase where the population is maintained at the constant level. This means that once a population achieves a maximum value it becomes stable where the growth rate is equal to the death rate. So, the correct answer is option A.
