genus and species of bacteria

It is a positive interspecific interaction in which members of two different species favour the growth and survival each other and their association is obligatory. Both the partners are benefitted by this interaction and it is a short or life long association as a means of obtaining food..

It is an antagonistic interspecific interaction in which one species is inhibited while other species is neither benefitted nor harmed. In simple words, in amensalism, one organism does not allow other organism to grow or live near it. It is also called antibiosis and the affect..

The plant hydrangea can have pink "flowers" or blue "flowers" (they're actually modified leaves). But we do not classify the two forms as different species. In fact, one could allow a blue-"flowered" plant to become a pink-"flowered" plant just by changing the pH of the soil and the amoun..

Characteristics of Biotic Community - A stable and self sufficient community has certain specific characteristics. a) Habitat Biotic community occupies particular area with specific physical environment, which acts as a limiting factor, regulating the population size of various species wi..

The process is the transformation of gaseous nitrogen into nitrates by living organisms. Biological nitrogen fixation occurs by: a) Symbiotic nitrogen fixation, which is brought about by certain bacteria such as: i) Rhizobium species in the root nodules of legumes (pea family) ..

t h century necessitated a thorough modification in the system of classification. A more systematic and scientific system called natural system of classification emerged. It was based on specific similarities and differences between organisms. The earliest attempt towards a natural system ..

Human evolution concerns itself with the emergence of humans as a distinct species. Undoubtedly, there are special features possessed by 'Homo sapiens' considered to be at the top of the evolutionary ladder but science has become fully committed to finding purely biological explanations..

Forests and Wild Life - The biotic component of our environment on land, i.e. plants and animals (leaving aside the oceans and other water bodies) are overwhelmingly found in forests. Forests form a buffer for the earth to protect life forms; in fact that's where all our biodiversity and including ..

Microbial resource is a resource not seen by naked eyes, like all other resource. But it is a powerful resource existing in all parts of globe - in atmosphere, on the earth, inside the earth, on the sea and inside sea, inside the bodies of animals and plants. Although large number of microbial ..

Organisms that synthesise, food with the help of the light energy of the sun, carbon dioxide and water by a process called photosynthesis are called photoautotrophic organisms. For example: Cyanobacteria (blue-green bacteria, prokaryotes), algae and all green plants. Organisms which synt..
