  1. Life as a phenomenon can only exist in the form of an ecosystem. And the ecosystem is based on food webs. In other words, any ecosystem should include three ecological levels of energy consumers – producers, consumers, and reducers.

    Precisely because it is IMPOSSIBLE to remove the level of consumers from the ecosystem, it is also impossible to remove predators (even of the first or second order) from it.

    The lack of understanding that Life is always an ECOSYSTEM often leads people to erroneous opinions. For example, some may assume that the primary protobionts were entirely heterotrophic and “fed” on the products of abiogenic synthesis (Oparinkovsky broth). Others suggest that the primary organisms were entirely photosynthetic or chemosynthetic… But both cases are IMPOSSIBLE in reality. The ecosystem must be balanced, otherwise it will self-destruct in the shortest possible time.

    Against this background, it also looks stupid to impose (usually by creationists) biologists to scientists, the idea of the RANDOM appearance of a SINGLE cell…

    At the current level of scientific development, it is clear that first an ecosystem was formed, with a division of ecological roles, and only then, individual intermediates (chemical RNA-containing hypercycles that divided the roles of producers, consumers and reducers) begin to put on shells – turning into cells.

    That's why in an ecosystem-PART of the organisms must always eat another part of the organisms.

  2. From the point of view of biology, according to the laws of this world, it cannot be otherwise.

    Life is an open system. Living matter, which should be understood as the totality of creatures that are still alive or were alive, but have already died and are decaying, consists of inanimate materials, organized in a special way. The way of organization of living beings is inherited by each of them in the genotype and passed down from generation to generation with minimal changes, which only cause further complication of living matter and the accumulation of inherited information. As a result, life not only uses inanimate substances and energy for its existence and expansion, but also does not release from its orbit already dying creatures that would otherwise have decayed again to inanimate materials. Among the few substances that can escape from a living system into outer space and not be re-drawn into the cycle of matter in a living system are only some gases, such as oxygen, methane, and carbon dioxide. Some elements, such as calcium and carbon, which can form solid substances, such as limestone, coal and peat, also sometimes avoid returning to the living system, but they do not go into space, but into the earth's interior; they remain on a planet inhabited by life, and may one day be reused by living beings.

    For life to grow and become more complex, it is necessary, first, that there should be a change of generations (in any way, not just by eating), and secondly, the extinction of poorly organized species (as they are expressed in politics, genocide) and their displacement by more highly organized and evolutionarily advanced ones. This does not mean, for example, that multicellular organisms will ever replace unicellular or acellular ones. A single-celled creature can be more highly organized than a multicellular one, if the criterion of high organization is considered not the number of cells, but the sophistication of the organization of the genome, which is present in both of them. So this question is only part of a more general question: why is life designed in such a way that it cannot do without death?

    However, since the question is asked in the topic “Philosophy”, the answer is incomplete if we consider the question only from the point of view of biology.

    Philosophy explains not so much the structure of this world (this is how philosophy differs from science, in particular, from biology), but the attitude of a rational being to it. Intelligence is a kind of by-product of life; the vast majority of living things do not need intelligence. It is not surprising that people distinguish themselves from the animal world and think of themselves as a model of some higher being, free from the burden of biological existence. That is why people sometimes ask such questions (unintelligent beings not only do not ask themselves whether they should exist or not, but do not ask any questions at all). The further course of the questioner's thoughts is not difficult to guess. Why did the Creator, if He is free from animal instincts and needs that are natural only to living beings, create us so cruel? Was He right? Can I correct It? Is there a way to be like the gods, immortal and free? Such questions were asked at the time of the creation of the first book of the Bible, and the biblical answer to them: the expulsion of Adam and Eve from paradise, so that when they ate from the Tree of Knowledge, they would not also eat from the Tree of eternal Life. In other words, man, know your place!

    But this is only a biblical answer. There are as many ways to philosophize as there are, or ever have been, people. Perhaps the highest purpose of each person is just to find his own answer to the question asked?

  3. At first, it wasn't designed that way. The first organisms fed themselves on sunlight. And until now, the main living mass is made up of plants that do not eat anyone. Here they have already created a sufficient concentration of energy for the emergence of a more active life-animals.

    And those breeding created a base for predators. And even for energy wasters like humans with their extremely voracious brains.

  4. Life is a high-energy process, and eating another living creature is one of the ways to get this energy for yourself and survive. But where do the people they eat get their energy from? They can also eat someone, but they can also eat something that is not alive, or that was once alive, but is now dead. In short, the usual food pyramid, which is considered in biology lessons at school.

    Why is that? Because. No one can answer such fundamental questions. For now. Evolution on our planet has taken place in such a way that many living beings must eat someone. Or maybe somewhere/sometime it turned out differently.

    Once again, I will make a reservation that not all living organisms eat someone. Plants almost all get their energy from sunlight. Cold-blooded animals also get it in the same way, but they also feed on other organisms in addition to this.�

    So, on Earth, there are several different strategies for how living organisms get energy, and indeed nutrients in general. Everything that could appear on Earth during the process of evolution, based on the initial conditions, has appeared.

    What are the alternatives? Except for nuclear and thermonuclear fusion. But these reactions are extremely poorly compatible with the processes occurring in living organisms)))

  5. Because the evolution of life, intelligence, and technology is possible only in Evil worlds-severely punishing for less relative fitness. Devour in the literal sense-brutal, of course. But this does not mean that other forms of victory in the struggle for existence are significantly better…

  6. In order to ensure progressive development through competition between species. This is laid down by higher forces to establish control over the Solar system.
