Question: wat r the unique survival tricks  developed by some insects.please explain by using examples.? pleazzzzzzz answer the question in details and please give at least 6 examples or more than tht still its ok if u give 1 example and it shud be very detailed i need it urgently fr my hhw plss

Answer: Here's some starts at least.  You still have to fill in the details; that's what homework is for.  Sorry, kid.\n\nEight Ways to Survive:\n\n1.  Reproduction, or in this case fecundity.  Many insects will lay thousands or even millions of eggs, to help ensure that at least some of their offspring will survive.  Someone once figured out that if every egg laid by one housefly were to survive, and if they all grew up to lay their own eggs, and if all those eggs survived, and so on, within one year the entire earth would be covered 6 inches deep with houseflies.\n\n2.  Rapid adaptability to changing environments.  This is part of fecundity.  With all those offspring, the genetic changes (mutations) happen more frequently, and so if there are any changes in the environment they can adapt more quickly as a species.  An example is a kind of gray moth somewhere in England.  Their wing color was perfect for them to blend in with the gray barks of certain trees.  Then a coal factory was built nearby, and the soot began to darken the barks of the trees.  The gray-winged moths were easy marks for birds and other predators, but the offspring that happened to have darker wings had a better chance to escape.  Within just a few generations, all the gray moths had changed to dark moths.  When the factory eventually shut down, and the soot started to wash and wear off the barks of the trees, guess what happened?\n\n3.  Which brings us to camouflage (hiding).  There are some pretty amazing examples of insect camouflage.  Google "katydid" and "stick insect" for a start.\n\n4.  Speed.  There's a kind of spider that lives in the desert.  It goes up to the tops of sand dunes, trying to collect moisture from the morning air.  But if a predator comes along, it curls up its legs and rolls like a pinwheel down to the bottom.\n\n5.  Symbiosis -- that's where two different species help each other out.  Did you know that some kinds of ants are actually ranchers?  They take care of a smaller species of insect called aphids, protecting them and helping them find food.  In turn, the aphids secrete a liquid which the ants use as food for themselves.\n\n6.  Strength.  Most insects have exoskeletons -- instead of bones, they have a hard, armor-like exterior to protect themselves against attack.\n\n7.  Speed.  There's a good reason why flies, mosquitoes and other flying insects move so fast and erratically.  It makes it harder for birds to catch them.  And many insects that don't fly can hop through the grass pretty quick.\n\n8.  Nastiness.  Thee's also a good reason why so many insects look creepy and icky:  To scare off/gross out would-be predators.  If that doesn't work, many insects have weapons of their own, claws, fangs, even venom.\n\nThere, that should give you enough to start with, at least.  You're still going to have to do some research work on your own.  Otherwise it woldn't be "homework," would it?  :o>
