1, different lifestyles:

An autotrophic lifestyle with photosynthetic pigments can produce organic nutrients for its own growth through photosynthesis. Heterotrophication is a way of life that absorbs organic nutrients made by other green plants for its own growth without photosynthetic pigments.

2. Characteristic differences:

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, the difference of classification:

Heterotrophication is autotrophic; Plants are basically autotrophic and animals are basically heterotrophic. Heterotrophication includes growth, parasitism and saprophy.

Data expansion:

As an ecological term, autotrophs are also called independent vegetative organisms, and the corresponding word is heterotrophs. Organisms that survive and reproduce by inorganic nutrition are the corresponding words of organic nutritious organisms. Organisms that assimilate carbon by using energy obtained from chemical dark reactions such as respiration or photochemical reactions are called chemoautotrophs and photoautotrophs respectively.

An organism that feeds on inorganic substances and can produce organic substances for its own growth. Including most green plants and chemosynthetic bacteria, they are producers of organic matter in the ecosystem and the basis of the food chain in the ecosystem.

Type:

An organism that can obtain nutrients and energy needed for its own life activities from the process of synthesizing organic matter from inorganic substances. Green plants, such as algae, mosses, ferns and seed plants, rely on their unique chloroplasts and use solar energy to synthesize organic substances from CO2 and water to feed themselves. Some chemically synthetic bacteria, such as nitrifying bacteria, sulfur bacteria, iron bacteria, etc. , can oxidize inorganic substances, using the energy released by oxidation to make the required nutrients.
