Problem description: As ...... the questionAnalysis:

As far as the population as a whole is concerned, they all have a few ears of chitin-accompanied exoskeletons. This exoskeleton protects the body on the one hand, and prevents the release of water from the body on the other. This is very important.

Because organisms evolved from aquatic to terrestrial, one of the problems that had to be solved was the loss of water from the body due to the drying of the land. For terrestrial invertebrates that do not have a chitin exoskeleton, they can only stay in relatively shady places, such as earthworms. Even amphibians among vertebrates can only stay near water due to their body surface.

Therefore, the problem of water retention has not been solved, which limits the living environment of the animal, so that it cannot become a truly free terrestrial animal. Insects, including other arthropods (insects are the main members of the large group of arthropods), are truly terrestrial invertebrates, and that's why: exoskeletons allow them to be found in all corners of the land, including deserts.

And this diversity of living environment, of course, has gradually evolved into a wide variety of types.

Secondly, they have segmented appendages that make them flexible in movement and sensation. Animals lower than them, although appendages, are not segmented, which limits the variety of animal movements. (Appendages refer to structures that grow from the trunk of animals with functions such as motor sensation, such as the feet, wings, and antennae of insects, the fins of fish, and the upper and lower limbs of humans.)

It's not hard to imagine what our lives would be like if we didn't have joints in our hands and feet. It can be said that in the animal kingdom, the first to use segmented appendages are arthropods (which is also the origin of their name), and subsequent animals must inherit this advantage and carry it forward if they want to surpass them. Different insects have different types of feet, which is suitable for their lifestyle.

Others, for example, have different mouthparts for different types and can be adapted to different foods; Diversification of reproduction methods, short reproduction cycles; Small size is also a factor, but it is not as important as chitin and segmented appendages.

The reason why insects are the most thriving group of animals.

1 Wings can fly.

Insects are the only winged group of invertebrates and the earliest group of animals to have wings. The acquisition of flight ability has brought great benefits to insects in foraging, courtship, avoiding enemies, and dispersing.

2. Strong fecundity.

Insects have an amazing ability to reproduce. Most insects lay eggs in the range of hundreds of eggs, with social and parthenogenetic insects have stronger fertility, if needed, a bee can lay millions of eggs in a lifetime, some people have estimated that if a parthenogenetic aphid all survive and continue to reproduce, the total number of aphids can reach about 600 million after half a year. Strong reproductive potential is the basis for a thriving population;

3 Small body advantage.

Most insects are small, not only a small amount of food can meet their nutritional needs for growth and reproduction, but also make them have many advantages in living space, flexibility, avoiding enemies, reducing damage, and migrating downwind.

1.Wings can fly 2Strong fecundity 3Small in size.

1.The earth is rich in food for insect consumption**.

2.The reproductive strategy of insects is the R strategy, that is, the number of eggs laid is large and the expansion rate is fast.

3.The short time taken for a generation provides a temporal advantage for variation.

Insects can emerge at all stages of evolution.

The words of a human are only produced by the highest primates.

The destruction of nature has not yet broken the minimum required limits of their survival!

Many of the behaviors and structures of insects are highly specialized in the direction of reproduction, for example, the adult of mayflies completely seals the mouth and digestive tract, and dies immediately after completing reproduction; Insect females such as praying mantis hunt smaller males after mating to provide nutrients for egg development; The male antennae of lepidopteran moths specialize into pinnae in order to more effectively sense female pheromones and complete the task of reproduction. Such a variety of reproduction methods and structures have also allowed insects to survive mass extinctions again and again, surrounded by natural enemies and crazy predation, unable to eliminate insects, insects are like a magic spell, and the huge number of birds can not shake their foundation no matter what kind of hunting. ‍‍

Insects are the longest class of classes on the planet so far, popularly speaking, a class of creatures, they were born earlier than dinosaurs, and they are also the first type of creatures to fly into the sky, the long evolutionary path gives them plenty of time, and the different living environment gives them unlimited possibilities. ‍‍

Most insects have winged structures, and the benefits of their ability to fly are incalculable: they are extremely maneuverable, far more than the groups that wriggle on the ground; Rapid expansion allows insects to spread to all corners of the world; Increased range of motion and field of vision, faster detection of prey tracks from the air, and more. And many insects have their wings folded without hindering their ability to move in confined environments or on the ground.

In addition, wings can be used as camouflage, gender displays, and even specialized as protective structures. ‍‍

It is natural that the decay of food will produce a lot of new insects.

They lay a large number of eggs, which is well understood. Secondly, they reproduce in a variety of ways: for example, in terms of the structure of the eggs, the eggs of the lacewings are fixed to the substrate by a slender stalk, the eggs of the cockroaches are protected by a hard egg sheath, and the cicadas are covered with special mucus.

In terms of the way eggs are laid, the eggs of mosquitoes float on the surface of the water like rafts; Parasitic wasps use special ovipositors to inject eggs one by one into the bodies of other insect larvae or animals; Locusts use their abdomen and ovipositors to work together to penetrate their eggs deep into the soil to protect them from predators. ‍‍

Natural selection of the fittest to survive. I think now the El Niño effect, and the global warming effect, has led to a rich diversity of insects.

Shorter fertility cycle, lifespan, so that genes can be rapidly renewed, more fertility means low survival rate, low survival rate means fierce competition, conducive to the survival of the fittest genes. ‍‍

They are extremely reproductive. The more offspring produced, the higher the success rate of reproduction. And insects are far more accomplished in reproduction than other animal groups. ‍‍

This is nature's choice, because we need so many insects in our ecosystem to maintain recycling and form an ecosystem.

The most important point: insects are very small. Many people don't understand and think that big is strong, but in fact, from the perspective of survival, it is not. ‍‍
