Dog, Cats, Horses etc. Legs Running, Walking
Birds, Bees, Insects Wings Flying
Snakes Skin Crawling
Lizards, Crocodiles Limbs Crawling

Plants are fixed at one place. They do not need to move in search of food, as they make their own food with the help of photosynthesis process. But they show movement in a special way. For example, wilting and swaying of plants, bending of sunflower towards sun light, growing of shoot system above ground and root towards ground, opening and closing of stomata in leaves, closing of leaves of mimosa pudica when touched etc. Non - living things can't move without the help of outside force.
