Which of the following represents a type II survivorship curve?
Step2247 [10]

Answer:

The correct answer will be option-C.

Explanation:

The survivorship curves are the representation of the proportion of individuals of the given species which are alive at different ages in the population of species.  The curves are represented in the form of a graph with the number of individuals plotted on the y-axis to the age of survivorship on the x-axis.

The survivorship curves are of three types: Type I, II and III out of which type three represents the population with equal probability of dying at all age groups. This is represented by a straight line on the graph.

Thus, Option-c is the correct answer.
