Answer:
The consumer is the main reason of the supply chain
Explanation:
Every activity of the supply chain (production, storage, distribution, sales, after sales service) is connected with the satisfaction of the customers and their needs or expectations, that means this is its general objective. A company also must have the best technology possible, a good internal and external communications channels, and the best human resources to reach this goal.
Answer: The choice of a submarine to either sink or float depends on the captain of that submarine. For a submarine to sink the captain just have to allow water to fill the water tank (lock), making the submarine more dense than the water it has displaced. For it to float, it just have to empty the water tank and allow air to fill it.
When a boat in a canal lock sank, the water level will rise, because the volume of the boat has displaced more water, and this displaced water will cause the water level to rise. The space occupied by an object in a water, is equal to the volume of water been displaced.
If demand is high and supply is low, the merchant should wait until more of the item is available. If you have any questions please ask!
