Muscle contraction is an example of mechanical contraction.
Explanation:
Muscular contraction is the activation of generating tension which appear in the muscle fiber as it does't change the length of muscle and is followed by muscular relaxation.
Muscle contraction is based on force and length.
The process of skeletal muscle contraction is an energy requiring process.
In order to perform mechanical work,actin and myosin utilizes the chemical energy into ATP that ultimately require during muscle contraction and relaxation.
In a working muscle,glucose is released from glycogen that are stored in the muscle by the process of glycolysis in which glucose broken down into ATP that is required by cells and tissues.
I’d say conical shape- coniferous trees are known for this shape.
