Label and explain each colored ring of von thunen's agricultural land use model. remember that each ring represents an agricultural activity and the purple dot in the middle represents the city, or epicenter. can someone me for 15

There are four rings of agricultural activity surrounding the city. Dairying and intensive farming occur in the ring closest to the city. Since vegetables, fruit, milk, and other dairy products must get to market quickly, they are produced close to the city (remember: they didn't have refrigerated oxcarts!). Timber and firewood would be produced for fuel and building materials in the second zone. Before industrialization (and coal power), wood was a very important fuel for heating and cooking. Wood is heavy and difficult to transport, so it is located as close to the city as possible. The third zone consists of extensive field crops, such as grains for bread. Since grains last longer than dairy products and are much lighter than fuel, reducing transportation costs, they can be located farther from the city. Ranching is located in the final ring surrounding the central city. Animals can be raised far from the city because they are self-transporting. Many animals can walk to the central city for sale or for butchering. Beyond the fourth ring lies the unoccupied wilderness, which is too great a distance from the central city for any type of agricultural product. Producing agriculture past this point would not be profitable.
