Which of the following best illustrates a type I survivorship curve, with higher death rates at older ages? Which of the followi

Rama09 [41]

Answer:

large mammals such as gorillas

Explanation:

The survivorship curves refer to the graphical representation of the proportion of the fraction of survivors or the individuals at a given age.

There are three types of survivorship curves which can be constructed by studying the life history of the organisms.

The type I survivorship curve is the curve which can be formed with the organism which has a high survival rate at the younger and middle age and high death rate at the older age. The type I curve can be characterised by its convex shaped. The type I is showed by the large mammals like gorilla, humans and many others.

Thus, large mammals such as gorillas are the correct answer.
