American photographers photographed blue herons eating crocodiles How fierce is the competition in nature?

In fact, the competition in nature is more intense than we thought. We just can't know or even understand nature through books or documentaries, because nature is more complicated than we think. Animals and plants living in it try their best to survive. If they are not careful, they may be eaten. This is unthinkable. If the American photographer hadn't accidentally taken this photo, everyone might not know. So blue is blue. People don't have a deep understanding of the laws of nature, because there are still many secrets waiting for us to discover, such as the competitive relationship and the intensity of competition, which need us to understand gradually; For many people, it may be known that the lion is the king of beasts, which can be said to be an animal standing at the top of the food chain, but everyone can't imagine that a lion can beat a group of wild dogs, even get injured all over, and even worse, die, which also makes people understand that groups are easier to win than individuals, and teams are more important; There are also some elephants that try their best to protect their children when they are chased by lions, tigers and cheetahs, while those animals that hunt are generally unsuccessful. Nature has always emphasized the law of the jungle, and only the strong can survive, but this sentence is not entirely correct. It is true that animals will do their best to survive, even in the face of opponents who are stronger than themselves, because time has allowed them to evolve and escape from hunters. Others seem to have no competitive relationship, in fact, because its existence will not threaten the survival of another species. Once threatened, it will stop immediately and there is no chance of growth. Such a relationship is mutually beneficial. Since you're doing it for my own good, don't? Kill them all? ; Nature is so cruel and beautiful.
