This document discusses the ways that animals and plants ensure the survival of their species. For animals, some ensure survival by caring for offspring, like keeping eggs or young in their mouths, pouches, or herds. Others protect their young by attacking intruders. Plants cannot move so their seeds are dispersed by wind, water, animals, or explosive mechanisms depending on seed characteristics like being light, winged, fleshy, or having hooks to attach to fur. These survival methods help prevent shortage of food resources and keep species from going extinct.
