Solution

The correct option is A True
Survivorship curves are good indicators of lives of animals, their growth rate, growth strategies, how much parental care they provide and how they survive. For example,in grey seal, they generally follow K strategy of growth. However, the males have to fight each other to find mates. This weakens them and makes them more vulnerable and an easier prey. Thus, more number of males die early and the curve falls more rapidly forming a type II curve, whereas there is greater survivorship among female seals forming a type I curve. Survivorship curves for male and female seals are given below:
