- Impacts of humans on ecosystems
- introduced alien species can escape into local ecosystems and become invasive
- species native - endemic
- species not native but introduced by man - alien species
- invasive species - if spread quickly
- Competitive exclusion and the absence of predators can lead to reduction in the numbers of endemic species when alien species become invasive
- pollutants become concentrated in the tissues of organisms at higher trophic levels by biomagnification
- biomagnification - chemical substances become more concentrated at each trophic level
- Macroplastic and microplastic debris has accumulated in marine environments
- gyres
- introduced alien species can escape into local ecosystems and become invasive
