What is the connection between adaptation and fitness

an individual with high fitness produces more offspring and therefore passes on its genes more frequently than an individual with low fitness. What is the connection between adaptations and fitness? Adaptations increase an organism's fitness in its current environment.

Explanation:

In biology, adaptation has three related meanings. Firstly, it is the dynamic evolutionary process that fits organisms to their environment, enhancing their evolutionary fitness ... Adaptation is related to biological fitness, which governs the rate of evolution as measured by change in gene frequencies.
