Life history trait:

Life history theory explains how specific developmental stages require organisms to differentially allocate limited resources to navigate various aspects of growth, survival and reproduction.

Life history is based on the natural selection.

All organisms need energy and nutrients to grow, survive and reproduce. These resources are limited, and there exists competition between organisms to use them.

In order to use those resources for growth, reproduction and survival, the organisms maximize their fitness. It also depends on the number of offspring’s the organisms produce for next generation.

Organisms with inherited traits that make use of the resources effectively will produce more offspring’s for the next generation; those lacking the traits will not survive, causing only the best traits selected by nature over generations.

Over long period of time this results in the collection of life history traits. These traits are well adapted for the environment

Answer:

Which of the following statement is INCORRECT regarding life history traits?

C. Life history strategies are determined by allocation of energy and resources between growth and reproduction, but nothing to do with an organism’s survival.
