Are frogs amphibians? What does it mainly live off by predation?

Frogs are amphibians, they live in the water when they are young, and they can also live on the shore when they grow up, and they mainly feed on insects, and they are also an animal that is more beneficial to humans.

Frogs are amphibians, and they mainly live by preying on various pests in the fields, so frogs are also a beneficial animal for humans.

Personally, I feel that frogs are amphibians, and generally prey on grasses, insects, insects, birds, snakes, etc., to sustain life with these things.

Frogs are amphibians. It mainly feeds on mosquitoes or some field pests.

Frogs are amphibians and vertebrates, frogs lay eggs in the water when they are young, and then they become tadpoles after hatching, small tadpoles cannot live on land, they need to grow in water all the time, and at this time they have to use their gills to breathe. After that, it slowly grows into a frog form and breathes with its lungs.

The habits of frogs.

1. Temperature frogs are ectothermic animals, and their body temperature changes with the change of external temperature. Under natural conditions, the suitable temperature for frog growth is 20-30, and the optimal temperature is 25-28. When the winter temperature drops below 10, feeding and activity gradually decrease. When it drops below 5, it burrows into a cave or hibernation in the silt at the bottom of the pool.

The following year, hibernation ends in early spring when the temperature rises. When the water temperature exceeds 32 or above, the activity decreases significantly. Temperatures above 35 will cause frogs to die one after another.

2. Humidity and humidity are an important factor in the survival and growth of frogs, because the tissue structure of frogs does not protect the evaporation of water in the body, and it is obviously not enough to rely on the mucus secreted by the gland to eat the humidity on the body surface. Therefore, the frog's habitat should be both a pond with water and a warm and humid environment with weeds.

There is a close relationship between humidity and temperature, the higher the temperature, the higher the humidity, otherwise the high temperature and dry environment, and the rapid evaporation of water is not conducive to the growth and survival of frogs.

3. Light frogs are nocturnal and afraid of direct sunlight, but they tend to be weak in light, and usually like to inhabit in sunny and shaded grass. Light has a promoting effect on the metabolism, growth and reproduction of frog body, such as living in the dark for a long time, its gonads are difficult to develop and mature, and even stop laying eggs and ejaculation.

Of course, adult frogs can live both on land and in water.

Yes, amphibious.

The larvae of frogs live in water, and adults can live both in water and on land.

Yes. Frogs are indeed amphibian. You can refer to the taxonomic definition of amphibians.

Yes, it can survive on land and in water.
