Which population of organisms would be most likely to show a Type I survivorship

Question

Which population of organisms would be most likely to show a Type I survivorship curve? Dolphins, which care for their offspring until adulthood and remain with them Birds, which care for their baby offspring, but which face many dangers as adults Oak trees, which produce millions of acorns, of which only a few germinate Corals, which produce millions of tiny larvae that travel on ocean currents Frogs, which produce millions of eggs and leave them in nests in pond sediment Which population of organisms would be most likely to show a Type I survivorship curve?

Explanation / Answer

Correct answer is -

Dolphins, which care for their offspring until adulthood and remain with them.

Explanation

Type I survivorship curve is a convex curve on the graph having time plotted on x axis v/s percentage of surviving population on the Y axis . This type of curve is observed in those species of animals which take good care of their young ones until the middle age . Species like humans and Dolphins show this type of curve with high population of middle age members and decline in population with old age .
