Saprophytic nutrition- the mode of nutrition in which organisms derive their food from dead and decaying plants

Yogita Ingle 5 years, 6 months ago

The different modes of nutrition include:

  • Autotrophic nutrition: In the autotrophic mode, organisms use simple inorganic matters like water and carbon dioxide in the presence of light and chlorophyll to synthesize food on their own. In other words, the process of photosynthesis is used to convert light energy into food such as glucose. Such organisms are called autotrophs. Plants, algae, and bacteria (cyanobacteria) are some examples where autotrophic nutrition is observed.
  • Heterotrophic nutrition: Every organism is not capable of preparing food on its own. Such organisms depend on others for their nutrition. The organisms which cannot produce food on their own and depend on other sources/organisms are called heterotrophs. This mode of nutrition is known as heterotrophic nutrition.
