Final answer:
Organisms in a population compete for resources, but the best equipped organisms don't always survive. Variation of traits exists within a species and advantageous traits spread through natural selection over time.
Step-by-step explanation:
Organisms in a population must compete for resources in order to survive. This is known as intraspecific competition, where individuals of the same species compete for limited resources.
The statement that the best equipped organisms survive is false. Natural selection does not always favor the fittest individuals. Sometimes, less-fit organisms may possess traits that help them survive and reproduce in certain environments, leading to the spread of those traits in the population.
Organisms of the same species do not have identical survival skills. Variation of traits occurs among individuals within a population, and some traits may provide advantages for survival and reproduction.
Over time, beneficial variations of an organism will spread through generations and gradually change the population as a whole. This process is known as natural selection and is a key mechanism of evolution.
