With regard to various food chains operating in an ecosystem, man  is​ consumer

Explanation:

• The term food chain refers to an ecosystem cycle, in which one organism consumes another, and another organism consumes it. It begins with the main source, such as sunshine and thermal winding, where producers (plants) make food, continues with consumers/animals consuming the foods, &ends with top predators. 
• Humans are at the top of the food chain, although they are generally omnivores. Human beings are consumers as they feed (or consume) animals or products from organisms. Since man himself cannot produce the food, he relies on food plants (producers).
• There are many trophic layers in a food chain. Plants are the major producers in this regard. The largest trophic level is occupied. Animals are considered primary consumers who eat vegetables & plants and are known as herbivores.   Secondary consumers are  animals consuming primary consumers are known as  carnivores.  Animals eating secondary consumers are known as tertiary consumers.    In the food chain man is the primary consumer, eating both vegetables (herbivores) & secondary foods (carnivores), and eating fish &meats.
