Stavka koja se može prevući		Odgovarajuća stavka
r-selected species		Many offspring all at once, minimal parental care
K-selected species		Mature early, smaller in size
K-selected species		Few offspring, high level of parental care
r-selected species		Most survive to old age

an organism that opens doorways

an organism that the ecosystem doesn't need and only causes harm to other organisms
