Explanation:

Ans

1) For many animals, the ability to move is essential for survival and, as a result, natural selection has shaped the locomotion methods and mechanisms used by moving organisms.

2)Hop, skip, jump, run, slither, slide, glide, fly, swim, burrow, climb, soar, hover, creep, crawl, wiggle – the list of ways animals move is endless.

3)They move with the help of three pairs of legs. The muscles near their legs help in such movement.

4)Since they don't have legs they use their muscles and their scales to do the "walking". Serpentine method: This motion is what most people think of when they think of snakes. Snakes will push off of any bump or other surface, rocks, trees, etc., to get going. They move in a wavy motion.

Answer 2

1) Animals show movement as unlike plants they can’t create their own food and for food they need to move and get it. Also they give response to stimuli and they have very much developed brains.
2) Crawling, Walking, Quadrupedalism, Locomotion, et cetera.
3) By Quadrupedalism
4) No, absence of limbs doesn’t restrict thir movements, they move with the help of their scales present on their body. In poems snakes are often referred to as slithering beauty as their movement is often called slithering.
