A farmer decides to allow apple picking on his farm. Which group is involved in this distribution channel?

Retailers typically buy products from producers or wholesalers to sell them to consumers. In the case of apple picking, the farmer is not selling the apples through a retailer but is allowing customers to pick the apples directly from the farm. Therefore, retailers do not play a role in this specific distribution channel.

Agents act as intermediaries who facilitate transactions between producers and buyers but do not take ownership of the product. In the apple picking scenario, there is no need for agents since the farmer directly interacts with the customers, eliminating the intermediary role that agents would normally play in traditional sales channels.

Brokers are intermediaries who negotiate transactions between buyers and sellers, often for a commission. Like agents, brokers are not involved in the direct selling process of the apple picking experience. The farmer's direct relationship with customers negates the need for a broker in this situation.
