1. Do frogs eat fish?
In a series of articles on One Hundred Thousand Whys in Life, I once said that "frogs only eat small bugs, not fish", but the fact that I encountered a frog eating fish in a pond slapped me in the face. I caught a frog in the pond, squeezed its belly hard, and a bunch of small fish came out of its mouth. Only then did I realize that frogs eat fish. Think about it, as a species that can reproduce on the earth for tens of thousands of years, it must be able to adapt to the complex earth environment. Its diet should be very wide. It has such a big mouth, and it can only swallow small things. Small mosquitoes, fish, shrimps, birds, flies... As long as it can swallow any animal, it can probably eat it. Who said that toothless animals can only swallow food the size of particles? That snake has a big mouth and can swallow all kinds of animals, big and small!
2, frogs, turtles, snakes, giant salamanders , species transformation conjectures of lizards
If you look closely, you will find some similarities in their body shapes, such as smooth triangular heads. If you remove the body and only look at the head department, sometimes confusing them. This makes people wonder whether they are the product of species differentiation?
Incredible conjecture: when a salamander grows a shell, it becomes a turtle; when a salamander takes off its tail, it becomes a frog; when a salamander lands, it becomes a lizard; when a lizard removes its limbs, it becomes a snake. Differentiated species often represent various states of evolution, and species in each state survive in their own ways. Are there shelled lizards or snakes (resident snakes) that evolved from turtles?
3. What is the basic growth process of grass?
Grass seeds germinate → stick to the ground and divide into radial leaves → continuously lift up and produce multiple layers of leaves → sprout branches at high places and bloom and bear seeds → grass seeds mature and downy grass seeds are sown in the wind.
The young grass we see at first can be seen as a top view or single-layer structure of the adult grass. With this understanding, we can distinguish what kind of young grass the adult grass comes from?
4. Eating rules of animals and plants
When young, they are eggs (seeds), which can be eaten all over the body;
When young, they eat skin and meat, but bones (branches) are not tasty;
When young, they eat skin, flesh, and fruit pulp;
When they are middle-aged, they eat seeds;
In short, as the age increases, the edible parts decrease, the tough parts are inedible, and the soft parts are often edible.
