The special function of the frog, the ability and role of the frog.

Yes. The larvae of the frog, the tadpole, live in water and breathe with gills. Adults can live both in water and on land, breathing with lungs and assisting breathing.

Because the frog's lungs are too small and their respiratory function is not sound, ** naturally takes on this important responsibility. It can be noted that the frog's ** is always moist, which is necessary for its ** to breathe.

When hibernating, the frog only breathes and does not use the lungs.

But note that frogs can only use ** to assist breathing when they are on land, and in the water** stomata will automatically shrink to avoid water ingress and cannot help breathing.

The breath of a frog.

Amphibians use three ways for gas exchange: mouth, mouth, and lung respiration. Frogs and toads rely more on lung respiration than newts, but the epidermis provides an important supplement to the gas exchange of tailless species, especially when winter comes, and they need to breathe when they are hibernating.

However, even under normal conditions, most of the carbon dioxide is released from the epidermis while the lungs are getting oxygen while the lungs are taking on breathing. Frogs are forced to bring air into the lungs by positive pressure (unlike people who use negative pressure), and during their breathing, mouth breathing and lung breathing are staggered, but the frequency of mouth breathing is greater than that of lung breathing. Although the frog also uses its lungs to breathe like us, its lungs are not developed, just a pair of thin-walled sacs, the structure is very simple, and the amount of gas exchange is very small.

The frog's ** often secretes mucus and keeps it moist, so that the oxygen in the outside air and the carbon dioxide in the ** microvascular blood are exchanged to supplement the lack of lung breathing. The oxygen obtained by frogs through ** breathing accounts for about 40% of the total oxygen intake.

Frogs are the "strongest" predators of pests and the most effective helpers of human pest control. Some experts have observed and studied that frogs have a very mixed diet, eating not only flies and mosquitoes, but also borers, mole crickets, leafhoppers, rice planthoppers and other pests. Frogs can eat more than 100 pests a day during the larval (tadpole) stage and more than 70 pests a day when they mature.

A frog can eat 50,200 pests a day and about 15,000 pests in seven months. Each frog preys on more than 15,000 pests a year, and frogs play an important role in protecting the ecological balance.

Frogs eat pests.

Frogs eat a lot, a frog can eat more than 70 pests a day, and can eat more than 10,000 pests a year, frogs are the natural enemies of agricultural pests, and there are many benefits to humans.

Without frogs, crops would be damaged, yields would be reduced, and human survival would be affected. Animals that feed on frogs in nature are also affected. The biological food chain mentions that if the food chain is broken, then the ecology will be unbalanced in the long run.

Frogs eat a lot, a frog can eat more than 70 pests a day, and more than 15,000 pests a year.

Even if you look at it, you will be affected by the French accumulation of particles.

I don't know, but I do know that frogs are beneficial insects.

It has 4 feet, two eyes, a mouth, and a tongue in it, which can be eaten, non-toxic, harmless, and will not be poisoned if you eat too much! It will also bark. The sound is:

Quack, not quack, not Wangwang, not baa! Its name is frog ..Got it?

Describe a boy who looks like that.

Frogs can maintain ecological balance. As a member of the biosphere, we have the right to survive and reproduce, and we should be protected and cherish life, which is the eternal theme of human beings.

Frogs have an amazing ability to catch pests, so they can better control pests in farmland and greatly improve crop yields. At the same time, the use of chemical pesticides is reduced to achieve biological control and protect the ecological environment.

Protecting frogs is also protecting biodiversity. Biodiversity is a precious natural heritage and a condition for human survival.

Protecting frogs is also protecting the food chain and food web, maintaining the balance of the ecosystem.

In short, to love living things, to love life, to love the environment, is to love us human beings.
