These are bacteria which are unable to manufacture their own organic food and hence are dependent on external source. These bacteria can be distinguished into three groups as follows: Saprophytic Bacteria: These bacteria obtain their nutritional req..

'Auto' means self and 'trophic' refers to food. So, the organisms which synthesise their own food are called the autotrophs and the process is called autotrophic nutrition. Autotrophs include all green plants and some bacteria such as the nitrifying bacteria. The sourc..

'hetero' refers to other or different and 'trophic' refers to food. Thus, the organisms that obtain their food from other organisms are called heterotrophs and the process of obtaining the food from other organisms is called heterotrophic nutrition. All heterotrophs depend directly or in..

Autotrophs synthesize organic materials from inorganic materials. Some organisms derive their energy for this process from sunlight and are called photoautotrophs. Example: Green plants Other organisms use chemical energy and are called chemoautotrophs. Example: Nitrifying bacteria. Phot..

Nutrition in Amoeba - Nutrition in amoeba is holozoic. Thus, solid food particles are ingested which are then acted upon by enzymes and digested. It is an omnivore, feeding on both plants and animals. Its diet includes bacteria, microscopic plants like the diatoms, min..

'Hetero' refers to other or different and 'trophic' refers to food. Thus, those organisms which obtain their food from other organisms are called heterotrophic and the process of obtaining the food from other organisms is called heterotrophic nutrition. All the heterotrophs depend directl..
