Verified step by step guidance

1. Understand the concept of 'fitness' in the context of natural selection. Fitness refers to an organism's ability to survive and reproduce in its environment, passing on its genes to the next generation.
2. Consider the role of survival in natural selection. An organism must be able to survive in its environment, which includes finding food, avoiding predators, and coping with environmental conditions.
3. Evaluate the importance of reproduction. An organism's fitness is also determined by its ability to reproduce successfully, ensuring that its genetic material is passed on to offspring.
4. Analyze the factors that contribute to an organism's survival and reproduction. These can include physical traits, behaviors, and adaptations that enhance its ability to thrive in its specific environment.
5. Reflect on why other attributes like speed, intelligence, or strength might be beneficial but are not the sole determinants of fitness. These traits can contribute to survival and reproduction but are context-dependent and vary across different environments and species.
