How do ants know not to keep building an anthill? How do they know when to stop?
Answer from: Yanina:
probably all related to the total number of ants, accordingly the size will increase as the number increases.
I think that ants begin to build an anthill, as bees - a good place to live. they all start to build it. make a place for their producers of future offspring and serve them. Well, the number of anthills grows in proportion to the amount of food that is available in a radius equal to the distance that an ant can travel in 40-50% of its working day. Like, to get there and back in time to go.
Lots of food - lots of offspring - need more needles for all. Over the years, probably the coefficient of usefulness of the territory in a radius of one ant goes down, and some of the young ants rushes to more fruitful territory, making a new anthill.
But that's just my theory.
- Why do dogs howl before their master dies? How do they know a person is going to die? What scientists think about it?
- How do hedgehogs keep their needles in place? How are they "attached"? Do hedgehogs change needles during life or not?
- They say that this is the sixth global extinction, and what about the previous five extinctions (I only know about the extinction of the dinosaurs)?
- When animals (cats, dogs) see their owners having sex, they know what's going on?
- Why do cats, dogs, etc.etc. look into the eyes of man? How do they know to analyze the face and not the hands or other parts of the body?
