What are heterotrophic and autotrophic?
First of all, both are ecological terms. Self-reliance is simply to support yourself.
Autotrophic organisms live and reproduce by inorganic nutrition. They use the energy obtained from chemical dark reactions such as respiration or photochemical reactions for carbon assimilation. Autotrophic organisms are divided into chemoautotrophic organisms and photoautotrophic organisms.
Representative examples of autotrophic microorganisms are red sulfur-free bacteria, red sulfur bacteria, green sulfur bacteria, nitrifying bacteria, sulfur bacteria, hydrogen bacteria, iron bacteria and so on.
Heterotrophication is a way of life corresponding to autotrophy. Heterotrophs refers to those organisms that can only use the ready-made organic matter in the external environment (organic matter is produced by autotrophs) as energy and carbon sources, ingest these organic matters into the body, convert them into their own components, and store energy.
Comparison between autotrophic and heterotrophic
1, different lifestyles
Autotrophic-a life style with photosynthetic pigments, which can produce organic nutrients needed for its own growth through photosynthesis. Heterotrophication-a lifestyle that grows without photosynthetic pigments by absorbing organic nutrients made by other green plants.
2. Differences in characteristics
The obvious feature of autotrophs is that they can synthesize organic matter for their own life activities without consuming ready-made organic matter. At the same time, it provides a large amount of organic matter for consumers (organisms that can't synthesize organic matter by themselves, but can only maintain their own life activities by consuming ready-made organic matter) and decomposers (organisms that need to decompose organic matter to maintain their own life activities).
3. Classification differences
Heterotrophication is autotrophic; Plants are basically autotrophic and animals are basically heterotrophic. Heterotrophication includes growth, parasitism and saprophy.
