In the video about GVC 4, traits, natural selection, and ecosystems are discussed.
Traits are characteristics that organisms have, which can be inherited or acquired.
Natural selection is the process by which certain traits become more or less common in a population over time due to their impact on survival and reproduction.
Ecosystems are communities of organisms that interact with each other and their environment.
