What is mutualism About mutualism Mutualism may be defined as a close association between two living organisms of different species which is beneficial to both the partners. Example 1-                        mutualism is the association of algeie and fungi to form lichens  in this association fungi provide the framework moisture and attachment sites and algal cells grow and synthesize food for both themselves and the fungi. Example2-                         Mutualism interaction between the flagellate protozoan - Trichonympha and wood eating termite is very interesting .These two species cannot live without each outher . :- The protozoan lives only in digestive tract of the termite and digest cellulose . The termite provides essential habitat constant environment and the besic food matteria  for the protozoan and the protozoan ...

What is carbohydrates  In short Carbohydrates  >                Carbohydrates are our body fuel . just as a vehicle burns petrol, diesel , and a steam engine burns coal ,  the body burns carbohydrates for energy . Our body uses up energy when we talk , walk or play or do anything with it. Our body needs energy even when we stand-up or sit-down and rest - we need energy to breathe , to circulate blood, to digest food , or to maintain our body temperature . So carbohydrates should burned to keep the body going The best source of carbohydrates is Rice .

About               Commensalism     Commensalism is a close association between two living organisms of different species which is beneficial to one and doesn't affect the other (host) Example1-                   Remora-shark relationship where remora fish (Echenis naurates) attached to the skin of the shark by means of strong sucker disc and transported to long distance at a faster speed by sharks motive power .  - The remora also consumes food remnants cost of from the raws of the shark . Thus the remora benefits in two ways from this attachment. Example2-                    an orchid growing as an epiphyte on a mango tree gets shelter and nutrients from mango tree while the mango tree is neither be nefitted not harmed.

Competition :- Definition >> Compilation occurs when closely related species compete for the same resources that are limited.           Or    The manual utilisation of limited resources. 1 The various resources for which competition occur may include space , food , nutrients, light , waste etc.              Competition may be classified into two types                   1- Inter specific competition                   2- Intra specific competition                           Inter specific competition:- 1- it is the competition between the individual of two or more different species . seeking the cnclilable resources such as food light space or shelter.   Example1-                      ...

                                Parasitism What is parasitism>> >> Parasitism is a close association between two living organisms of different species which is beneficial to one species (parasite) and harmful to outher species (host). - parasite which live on the other surfaces of the hosts are called  ectoparasites.   Example- ticks , flash , leechers etc..  - The parasites living within the host body are known as endoparasites,. Example-    tapeworm ,  liver , fluke , plasmodium etc...     Adaptation of parasites 1- parasite show absence and degeneration of feeding and tocomotory organs Example- fasciola and Taenia (tapeworm). 2- Green parasite plants develop haustoria  Example-( cuscuta ) to absorb nutrients from the host . 3- several fungi and pathogenic parasites infecting mammals and birds , secret exoenzymes to digest host t...

1 What is genetical engineering ? 2 what are the advantages of genetically modified foods? 3 what are their disadvantages? 4 what do consumer groups around the world demand ? >> What is genetical engineering and why are consumer groups up in arms against such genetically modified foods or gene foods? Well to put in a nutshell , it is a process of extracting gens bearing a specific hereditary trait from one organism and artificially inserting them into a completely different organism.     There are several possible benefits from such genetic engineering . You could have foods whose nutritional values are enhanced . Scientists, for example are reported to be working on iron and vitamin fortified rice.      Similarly you could develop crops that are resistant to pests and giving higher yields , or those that survive extreme weather conditions . You could even provide edible vaccine through such engineering.    But on the outher hand , w...

Bamboos are grown largely in western ghats and North east side . It nearly covers almost 10 million hectares of India's jungle area. More than 100 species are living in jungle ,( about 30 -40 metre tall bamboo are find here. Dendrocalamus giganteus are about one better high ,  Acundinaria densifolia with an 8 millimetre girth, are found in our India .) We produce about 3.2 million tonnes of bamboo annually .                       More than 50% of Bamboo is turned into paper,  the outher uses of plant has - making weapons part , construction material , bamboo tools and also for food . In the Monpas of Assam making a suspension bridge with the uses of bamboo . And  in Bihar bamboo is replacing plastic and metal tube , because it is cheap, more durable , rust-free and it is the best thing for poor farmers who never buy a tube or pipe ., Allahabad rehabilitation centre (viklang Kendra) for the handicapped, they makes m...
