The basis of judgment:
The concept of autotrophs is that organisms that can synthesize their own organic matter from inorganic substances belong to autotrophs. Autotrophic organisms do not need to add another carbon source, and the carbon source is CO2.
The concept of heterotrophy is that you can only take in organic matter from the outside to synthesize your own organic matter. The key difference between inorganic matter and organic matter is whether it is inorganic carbon or organic carbon.
Types of autotrophs:
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.
Types of heterotrophs:
An organism that cannot synthesize organic matter by itself, but must take exogenous organic matter as food and obtain energy by decomposing and oxidizing organic matter. Include animals, general non-chemical bacteria and fungi. They are consumers of organic matter in the ecosystem.
The difference between autotrophs and heterotrophs;
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. 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.
