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.
516 POSTS. Heterotrophic nutrition is nutrition obtained by digesting organic compounds prepared by other plants or animal tissues. All animals and non-green plants cannot make their own food; hence they depend on others directly or indirectly for their food supply. They are called heterotrophs.They break down the complex compounds into simpler forms. Simply put, heterotrophs have to depend on other sources for their survival.owever, sometimes the organisms position itself on the surface of the hostâs body, probably the skin and derive the nutrition, such types are called ectoparasites. Mosquitoes and leeches are the perfect examples of parasitic nutrition in which they suck out blood as nutrition from the hostâs body surface.
