The presenter defines biotic factors and explains how they can affect communities and ecosystems. The focus is on living factors, such as availability of food, arrival of new predators or pathogens, and competition between species. The presenter gives examples of how biotic factors have impacted various communities and ecosystems, including the decline of the red squirrel in Great Britain due to competition with the grey squirrel, and the impact of the varroa mite on bee populations. The video concludes with an example scenario of how the release of a new predator, such as a mink, can affect a community.\n
