How is the symbiosis of ungulates and cereals expressed?

This case is a classic example of mutually beneficial coexistence of different species in biogeocinosis. Cereals for ungulates are the main source of nutrients and, accordingly, the main food base. Ungulates, in turn, passing through the field, spew excrement from the body, fertilizing the soil with them. After all, fertilizers are one of the determining factors for the growth of cereals. In addition, in a similar way, animals promote the spread of cereal seeds, so that they can explore “new territories”.
