Question

Is a pig biped or quadruped? Why?

Answer 1

A pig is a quadruped, meaning it has four legs and walks on all fours.

Step-by-step explanation:

A pig is a quadruped

. Quadrupeds are animals that have four legs and use them for locomotion. Pigs, like other mammals such as dogs and horses, have evolved to walk on all fours to support their body weight and move efficiently.

Answer 2

A pig is a quadruped, using all four limbs to support its body weight and move, unlike bipeds like humans that walk on two legs.

Step-by-step explanation:

A pig is a quadruped because it sustains its whole body weight on all four limbs (two forelimbs and two hindlimbs) when moving.

This type of locomotion is common among many mammals, as it provides stability and support. Hoofed animals, which include pigs, have adaptations like hoofs that allow them to efficiently support their body weight while moving.

Comparatively, in bipedal locomotion, an organism moves by walking on two legs, having one leg on the ground while the other moves forward, as seen in humans.

Pigs do not exhibit this behavior and their anatomical structure, with a broader base provided by four legs, supports a quadrupedal mode of movement.
