Source: Ouyang Shan's "Sanjiaxiang": "He is a bit like Zhan Gong, too arrogant." There is no room for two tigers in one mountain, and a good girl doesn't marry Jiro.

Two tigers are not allowed in one mountain: tigers are solitary animals with strong territorial concepts. Once an outsider invades, the tiger will try to catch it. Tigers feed on large and medium-sized herbivores (mainly deer), but also prey on other carnivores at the top of the food chain, such as deer. Food chain: grass deer tiger Therefore, tiger is a highly nutritious creature with less energy and individuals. In order to get enough food to survive, there is a phenomenon that "one mountain can't accommodate two tigers".

Energy flow angle:

According to the characteristics and laws of energy flow decreasing step by step in the ecosystem, in the process of energy transmission along the food chain in the ecosystem, every link has consumption and loss, which leads to low energy transmission efficiency. The higher the trophic level of organisms in the food chain, the less energy can be used. Tiger is in the highest trophic level in the ecosystem, and the energy flowing through the tiger through the food chain (net) has been reduced to a very small extent. Therefore, to feed a creature with the highest trophic level requires a large number of producers, and a tiger needs a very large range of activities and predation space to survive. Therefore, "one mountain can't accommodate two tigers" has certain ecological reasons.
