Individuals living in the same area are referred as local populations. They all experience similar ecological processess at a particular stage of the life cycle. Similar populations of a species occupying different geographical areas are called sister populations. Population is a dynamic ..

This is a special case of functional isomerism. Certain substances can exhibit properties of two functional groups as for instance, acetoacetic ester behaves like a ketone as well as an alcohol. This arises due to the migration of a labile hydrogen atom from one place to another.In acet..

Lymph nodes are oval or bean shaped bodies placed in the lymphatic vessels. They act as filters and are sites where lymphocytes are formed. The main groups of lymph nodes lie in the neck, axilla, thorax, abdomen and groin. They help in the production of antibodies and in the development o..

The components of food are certain organic substances and minerals found in food. They are called nutrients. Nutrients provide the body with energy and enable it to grow, repair and maintain itself. Hence it is important that we understand the exact role of nutrients in our food and recog..

There are saprophytic organisms (mainly bacteria and fungi) that live on dead animals and plants. In terrestrial ecosystem, bacteria act on animal tissue and fungi on plants but there may be exceptions also. This group of organisms plays a vital role in releasing back the bioti..
