This document discusses physical adaptations in animals and plants that help them survive. It provides examples of physical adaptations for different species, including camels, bats, chameleons, stick and leaf insects, polar bears, hummingbirds, and humans. Physical adaptations develop over many generations and include traits like beak shape, fur thickness, skin toughness, limb length, and opposable thumbs. They help animals obtain food, stay safe from predators and weather, build homes, and attract mates. Plants also have adaptations for survival like cacti that can store water and deter grazing animals with spikes.
