Different types of autotrophic nutrition. Autotrophic nutrition is very important! Autotrophic nutrition means that simple inorganic substances are taken in and used to synthesise organic molecules. Energy is needed to achieve this. In photo-autotrophic nutrition light is the energy source. In most instances the light source is solar energy, the process being photosynthesis. Carbon dioxide and water are taken in by organisms and used to synthesise glucose, which can be broken down later during respiration to release the energy needed for life.
An autotroph is an organism that produces its own food. It is  usually a unicellular organism. Autotrophs utilize photosynthesis  to produce their food (typically the nutrie â¦ nt glucose). An  autotroph is also referred to as a producer.An example of an  autotroph is algae.A heterotroph is an organism that receives its  food from other sources. It is a multicellular or unicellular  organism.Organisms that are consumers or decomposers are  heterotrophs. A parasite is also a heterotroph. A parasite feeds  off other organisms for its food. An example of a parasite is a  deet tick. heterotroph is an organism that receives its  food from other sources. It is a multicellular or unicellular  organism.
