diversity and adaptations of organisms

These do not contain chlorophyll and hence are heterotropic and have diverse modes of nutrition. They may be saprophytic i.e., depending on dead or decaying organic matter for their food, or may be parasitic i.e., depending on living organisms for their food. Exam..

Gene Mutation - The variations at the level of the gene which form the basis of the differences between related organism as well as the diversity among organisms is called gene mutation. Gene mutation is defined as a sudden discrete change in the genetic material of ge..

Biodiversity Changes in an ecosystem Fluctuations in population size in an ecosystem Water, carbon, and nitrogen - cycle between abiotic resources and organic matter in the ecosystem Oxygen cycles via photosynthesis and respiration Stability of producers and decomposers in an e..

) or of destructive nature, involving the breakdown of an organic compound (catabolism). Living organisms exhibit various mechanisms for maintaining a constant state. Living organisms show adaptations to their surrounding environment. Living organisms..

Polymorphism is the phenomenon of occurrence of more than two forms of an individual within the same kind of organism. A colony is formed of more than two types of individuals, which differ in their structure, function and behaviour. Colonialism is found in insects and coelenterates. Pol..

i) The pelvic girdles join to form bowl like structure and the wide space enclosed between them forms the pelvis which support and protect the abdominal organs. ii) The pelvic girdles of female are more flexible, broader and shallower than those of male, this is an adaptation f..

One of the main ideas in the modified cell principle is that new cells arise from pre-existing cells (Omnis cellula e cellula). Every new cell formed must inherit not only the nucleus which contains the genetic information, but also should inherit the cell organelles that are required to express th..

Conservation of wild life has three objectives a) To maintain essential ecological processes and life supporting systems. b) To preserve the diversity of species or the range of genetic material found in the world's organisms. c) To ensure sustainable utilisation of species and..
