The fact that populations exist in a limited environment or niche.
All individuals in a population require food. But they need to expend energy to obtain sufficient food. There is only so much food to go around in a given area, and if the population grows to a sufficiently large size, then not every individual will be able to obtain sufficient food. Those individuals unable to muster the energy required to obtain the food required for them to survive perish. These are usually the old, the infirm or sick.
That is one way in which individuals within a population compete. But there are others: they may compete for mates, for instance. Individuals with attractive features are more likely to get the girl (or the boy). Attractive features may be those that enable them to provide more food. But they may also be entirely unrelated to survival skills.

What did darwin call the struggle for existence?
Natural selection.
What are the phases of Natural Selection?
The four stages are: Overproduction, Genetic Variation, Struggle to Survive, and Successful Reproduction
Is the struggle between organisms to survive in a habitat with limited resources is called natural selection true?
Quite true, but you can refine the definition ecologically speaking and say this is also a form of competitive exclusion.
What is the type of natural selection that favors intermediate phenotypes?
When natural selection favors the intermediate version of a characteristic, it is referred to as stabilizing selection. It is the opposite of disruptive selection.
Why do you think Darwin considered the phrase the struggle to survive an appropriate description of natural selection?
Darwin considered the phrase "the struggle for survival" because he observed that in nature, individuals must compete for limited resources like food and mates to survive and reproduce. Those individuals with traits that give them a competitive advantage are more likely to survive and pass on these advantageous traits to their offspring, leading to the process of natural selection.
What is the 4 main points of natural selection?
natural selection (4 tenants) -genetic variation -overproduction of offspring -struggle for existence (competition) -differential survival and reproduction
Is speciation a sub-process to natural selection?
Yes and so are successful reproduction and the struggle to survive.
