Qualitative data is when you can see the ecosystems. the importance of biodiversity for all sustainable ecosystems is biodiversity boosts ecosystem productivity whether each species, no matter how small, all have an important role to play.

Natural selection means that the organisms better adapted to their environment, that is, they have developed the right characteristics/skills/response to the external ambient, have higher chance to survive, making the next generations genetically inherit such acquired surviving characteristics.
These generations will thus have a higher chance of survival, making these species being "naturally selected" as survivors, while those who haven't or are slower in this process, have a higher risk of elimination.
