Unit-5 Shortnote

(1) Ants have Great Adeptness (skill) – Illustrate (Explain)
  • Science has found out that the ant has great intelligence and it is very close to human intelligence. 
  • Ants work with team spirit and with great skill. 
  • A scientist observed their following behaviour: 
  • When the bits of insects are taken to their anthill they find the sides of the pit were steep and the loads were heavy.
  • So they immediately organise the work. While some ants carry up the bits of insects, the others go in front to clear the way. 
  • Where there is difficult to get a foothold, they make an ant chain to take the load easily. 
  • The ants at the top began climbing down into the pit backward, each holding the tail end of another ant in front. 
  • When the ant-chain reaches the ants waiting with their loads, those ants easily climb up the chain and reach at the top.


(2) Different Kinds of Ants and their specialities
  • There are many types of ants in the world.
  • The umbrella ant of South America is called as ‘farming ant’. 
  • They are often seen carrying large pieces of leaf over their heads like umbrellas. 
  • They take a leaf to their nests, chew them up nicely and make a bed of this chewed up leaf. 
  • On these beds grows a fungus, which is the food of ants. 
  • Then there is another type of ants who domesticate ‘cows’ and ‘milk’ them. They take greenflies to their nests, nourish them and ‘milk’ them; by pressing the sides and making them give out their honey. 
  • The red ants that keep black ants as their slaves. 
  • The red ant attacks the nests of black ants and abducts some of their egg and takes them to their nests. 
  • When the eggs are hatched, the black ants come out are treated as slaves and they are forced to work.
  • They have to carry their masters on their backs. 
  • The most ferocious kind of ants is the “Driver Ants” of Africa. 
  • They are completely blind, and they walk in long lines. They can devour any animal that comes their way. 
  • Even large animals like tigers and elephants live in fear of them. 
  • If a python happens to come in their way, they eat both the python and the animal in its stomach.
  • If they enter in the house, the people run away in the forest.


(3) The Driver Ants  
(March 19) 
  • The “driver ants” of Africa are the most ferocious kind ants. 
  • They have no fixed home but they walk on in a line. They are completely blind.
  • They devour any animal that come in their path. 
  • Even large animals like tigers and elephants live in fear of them. 
  • They can even devour a python with the animal which is in his stomach. 
  • When an army of the driver ants enters a house, the people ran away into the forest and stay there until the ants have passed. 
  • When the people come back, they find that every insect and spider in their houses has been cleared away.
