The correct order of occurrence of event in ascending order (oldest to newest) is given below:
1. Organisms produce more offspring than the environment can support
2. There is increased competition for resources
3. Some organisms do not survive
4. Those that survive are better suited to the environment.
5. Organisms that survive reproduce, sending their genes into the next generation..
This sequential order is based on the concept of “Darwin’s Theory” of natural selections according to which the organisms reproduced are more than the resources available for their survival. Thus in scarcity of resources, the competition among the organism’s increases and then only the one which is able to best fit the nature survive. Those that survive further reproduce.
