Verified step by step guidance1
Understand the concept of locomotion: Locomotion refers to the movement of an organism from one place to another using its body. This process requires energy to overcome various forces.
Identify the forces involved in locomotion: The primary forces that animals need to overcome during locomotion are friction and gravity.
Explain friction: Friction is the resistance that one surface or object encounters when moving over another. In biological terms, it can refer to the resistance between the animal's body and the surface it moves on.
Explain gravity: Gravity is the force that attracts a body toward the center of the earth, or toward any other physical body having mass. Animals must exert energy to counteract gravity to move upwards or maintain balance.
Combine the concepts: Locomotion requires energy to overcome both friction and gravity, as these forces resist movement and require the animal to exert additional energy to move efficiently.
