Study Notes
Locomotion Mechanisms
- Animals that have evolved to minimize energy expenditure per unit distance are typically slow-moving, small-sized, and have a large surface area, such as snakes and earthworms.
Reasons for Animal Movement
- Animals move to achieve specific goals, such as finding food, escaping predators, breeding, and migrating to suitable living environments.
Evolution of Locomotion Methods
- The evolution of locomotion methods and mechanisms in moving organisms has been shaped by natural selection, where the most energy-efficient and effective methods have been favored.
Examples of Locomotion
Passive Locomotion
- An example of passive locomotion is the drift of seaweed and other marine plants, which use ocean currents to move around.
Active Locomotion
- An example of active locomotion is the movement of animals such as cheetahs, which use their muscles to generate force and propel themselves forward.
