<u>Answer</u>:
1. Organisms better adapted to their environment tend to survive
2. Organisms better adapted to their environment tend to reproduce and increase in number
3. Organisms pass on their traits to succeeding generations.

<u>Explanation</u>:
The concept of natural selection was given by Charles Darwin.
In his theory of natural selection the following postulates were given by Darwin:
1. Individuals within a species vary from one another.
2. Some of this variation is heritable.
3. Individuals with most favorable variations tend to survive better and produce more offsprings.
4. Individuals tend to reproduce and produce more offsprings than can be supported by the environment.
<em>Thus, based on these postulates all the four given statments are correct.</em>
