Producers are people who make a certain product and consumers are people who use a certain product.
For example, we all use smartphones in our daily life to make calls, to play games, and us a number of apps. However, most of us don't really makes these phones but their are companies that produce these phones for us.
So companies like apple, samsung, and vivo make these in factories.
Now similarly, many people love watching movies.
These movies are made by people from the film industry and the people from the film industry produce these movies for us so they make the movies which we watch which means that the people who watch the movies are the consumers and the people who make the movies are the producers.
We are also the consumers of food because we eat the food but we do not produce the food. Farmers grow food for us but they do not produce. They do this by growing plants and food is produced by these plants. In addition, many other animals besides humans are dependent on plants for food.
