Final answer:
Distribution channel activities commence with the manufacturer, who is responsible for creating products, which are then passed on through different stages such as wholesalers and retailers before reaching the consumer.
Step-by-step explanation:
The activities in a distribution channel process begin with the manufacturer. The manufacturer is the one who creates or produces goods. After production, these goods typically move through different stages of the distribution channel, possibly involving wholesalers, agents, retailers, and finally reaching the consumer. It's an organized network of agencies and institutions, which in combination, perform all the required functions to link producers with end customers to accomplish the marketing task. This channel is crucial as each member adds value to the product, making it more accessible and desirable to the consumers.
