Verified step by step guidance

1. Understand the concept of natural selection: Natural selection is a process where organisms better adapted to their environment tend to survive and produce more offspring. This concept was introduced by Charles Darwin.
2. Identify the levels of biological organization: The levels include individual, population, community, and ecosystem. Each level represents a different scale of biological organization.
3. Clarify the role of natural selection: Natural selection acts on the phenotypic variations among individuals within a population. These variations can affect an individual's ability to survive and reproduce.
4. Determine the level at which natural selection acts: Since natural selection acts on individual organisms based on their traits, it primarily operates at the level of the individual.
5. Recognize the impact on populations: While natural selection acts on individuals, the effects are observed at the population level over time, as advantageous traits become more common in the population.
