Fallen leaves and fruits
Some species of invertebrates, such as moths, butterflies, bees, snails, and spiders, rely on fallen leaves, as well as dead branches and fruits mixed with fallen leaves, as shelter for winter, and obtain food and warmth here.
Animals are a species of living beings. They generally feed on organic matter, can feel, can move, and are able to move autonomously or move. Including people.
According to fossil research, the first animals to appear on Earth originated from the ocean. After a long geological period, early marine animals gradually evolved into various branches, enriching the early life forms on earth. Prehistoric animals appeared before the advent of humans and flourished during their respective periods of activity.
Later, they became extinct one after another in a constantly changing environment. However, animals on Earth continue to evolve and reproduce from the lowest to the higher, from the simple to the complex, and have the diversity they have today. Scientists divide the extant animals known to humans into two major types: invertebrates and vertebrates, according to the presence or absence of a vertebrate in their bodies.
Scientists have identified more than 46,900 species of vertebrates. Including sharks, rays and other cartilaginous fish animals, carp, yellow croaker, grass carp and other bony fish animals, frogs, baby fish and other amphibians, snakes, lizards and other reptiles, chickens, pigeons, sparrows and other birds, monkeys, red pandas and other mammals. Scientists have also discovered more than 1.3 million species of invertebrates.
Most of these animals are insects, and most of the insects are beetles. Sponges, earthworms, squid, oysters, red starfish, jellyfish, spiders, polyps, radiolaria, roundworms, pork tapeworms, sand silkworms, snails, slugs, etc., are all invertebrates. The bodies of all members of the animal kingdom are heterotrophic organisms made up of cells.

Spiders have their own unique ability: weaving webs. The webs are very thin, with the thinnest being only 2 to 3 microns in diameter. Spider silk is stronger than steel wire of the same thickness. Spiders rely on their webs to catch insects.
Snail skills: Snails have shells and mucus that prevent water loss and stick to any place without falling off.

What do you mean? Snails have shells and mucus that prevent water loss and stick to any one place without falling off. Spiders can build webs to catch flying insects, and they can also throw their webs out to entangle their prey, and venomous spiders can quickly bite their prey to death. Do you mean that?

Praying mantises and spiders mainly feed on small insects, and some spiders feed on small mammals or birds.
Praying mantis will pretend to be its surroundings (e.g., dead leaves, young branches) and wait for its prey to come to its home.
Spiders like to be in dark and damp places, and many spiders will build webs.
Snails are the most toothed animals, feed on the leaves of many plants, and prefer dark, damp places.
Hope you help, my, thank you.

Spiders have many natural predators. Toads, frogs, lizards, centipedes, bees, and birds all prey on spiders, some parasitic wasps parasitize in spider eggs, some parasitic flies develop larvae in spider egg pouches, and small-headed gnatfly insects almost all parasitize into spiders in the form of larvae. Spiders often use a variety of methods to ward off enemies, such as ventilating venom, stealth, camouflage, mimicry, protective color, vibration, and so on.
When you can't escape, and your appendage is caught by the enemy, simply cut off your appendage and walk away, anyway, the self-cut step will regenerate when molting.

One winter day when the snow was flying, I went to the garden to build a snowman after lunch.
Suddenly, I saw a snail crawling with difficulty, and I took a closer look and saw that it was aiming for a small hole in front of it. The hole was so small that my little finger couldn't get in; The exterior of the cave is smooth, and snow will slide down when it falls on it. Although this snail was only three centimeters away from the entrance of the cave, it was a long way for it.
At that time, I was only five or six years old, and I was very curious about some interesting things, including snails, so I kept crouching next to it, and there was a half-stacked snowman next to it, which I had long forgotten.
Two o'clock, two and a half, three o'clock, and it still did not climb into its little hole. I got a little impatient and quickly grabbed it and put it in front of the hole. It "stood" at the entrance of the cave and stared in, but it wouldn't go in.
It turned its head to look at me, and then at its original position, and the whiskers on its head kept stretching and contracting, as if to say, "I almost got home by my own efforts, but you want to put me here at a critical time, and you won't put me back?" After a few seconds, it crawled back to where it had been.
I'm a little confused, why is it going back? I wiped my eyes, thinking I had just misseen, but when I opened them, it was still trying to return. I suddenly felt like a badass and ruined its dream of walking home on its own!
I put it back in its place, and the whiskers on its head retracted as if to thank me.
At that time, the snail told me that many things can be done without the help of others as long as you work hard!

There are not many small animals that can give us infinite revelations, such as the snail, who has a strong spirit. If you are afraid of difficulties and keep thinking about your goals, this is worth learning from us human beings. There used to be a story in Yichun about an 80-meter-high wall from which a small snail climbed.
One ran for three hours to keep his eyes open. This little snail was blown off by a gust of wind. But this little snail he will not give up, try to strengthen his beliefs, and the crowd climbed the 80-meter-high building within four hours.
This story of Nasha has left a deep impact on future generations. In this way, people who came after them were left with a heroic death. All the spirits of the saints are also strengthened by this snail.

Spiders weave webs day and night, not afraid of tiredness Although snails climb slowly, they can succeed in the end.

Is this an essay or something.

No, the habits are different.
Snails like to live in a dark and damp, loose and humic environment, nocturnal, most afraid of direct sunlight, sensitive to the environment, the most suitable environment: temperature 16 30 (23 30 hours, the fastest growth and development); Air humidity 60% 90%; The humidity of the feeding soil is about 40%; The pH is 5 7. When the temperature is below 15 and above 33, it is dormant, and when it is lower than 5 or higher than 40, it may freeze to death or heat death.
Spiders mainly prey on small insects. Spiders at the water's edge can hunt small fish and shrimp, bird-catching spiders can catch birds, and spiders also have the habit of killing each other. Nomad spiders actively pounce on their predators, while web-forming spiders hunt with webs.
Web-forming spiders have underdeveloped eyesight, but they are sensitive to shocks and can determine the size and location of catches through the vibrations of the silk. They hunt with chelicera, which contain venomous glands (with the exception of arachnidae and arachnidae), located within the chelicera, usually extending posteriorly into the head, with a tube opening at the proximal end of the chelicerae. The chelica pierces the catch, the muscles around the venom gland contract, and the venom is injected into the worm's body, which anesthetizes or kills it.
At this time, digestive juices are spit out from the mouth, injected into the wound of the prey, and the tissue is digested before being inhaled into the spider's body. Garden spiders and other species can wrap their catches with silk before or after a chelicerae bite, making them unable to move or fixed on the net. When hunting spiders hunt at high places in plants, they also use silk to wrap around their prey.
Spiders with non-venomous glands rely entirely on silk to bind their prey. There are a few species of spiders in 9 families that live in varying degrees of social life. Social spidersMultiple spiders share 1 web and cooperate to hunt.
Spiders do not hunt for food very often, but they have an adaptability, their metabolic rate is relatively low, they can tolerate hunger, and they can eat a large amount of food equivalent to their own body weight at a time, for example, tarantulas have a lifespan of about 305 days and can go without food for 208 days, during which their metabolic rate decreases by 30 to 40%.
The "troika" that drives economic development is exports, consumption and investment. In China's excessively high level of foreign exchange reserves and distribution, the RMB exchange rate is forced to appreciate, resulting in blocked exports, investment has always been the highlight of China's economic development, but investment is generally the leading large enterprises, which is now increasingly prominent economic structural problems in China is not beneficial, nor can it meet the needs of the people in the pursuit of social public services. Consumption, which is the most important driving force for the economic development of developed countries today, on the one hand, reflects the country's commitment to the people's wealth, hiding the wealth from the people, the people can only consume when they have money, and the needs of the people are met while consuming. >>>More
