Definition: Fitness in biology is how well an organism survives and reproduces in its environment, passing its genes to the next generation.

Examples:
- A fast gazelle that escapes predators and has many offspring has high fitness.
- A strain of bacteria that survives antibiotics and multiplies has higher fitness than sensitive strains.

Using it: The moth's fitness increased when its coloration helped it avoid predators.
