The performance is that any living thing can grow in size.
The so-called heterotrophic and autotrophic are just different raw materials and energy sources needed to synthesize their own ingredients.
It's like if we eat sugar, some of it will be converted into fat and stored.
Therefore, whether organic matter can be synthesized is not the criterion for judging autotrophic heterotrophy.
His criterion is only one: whether energy is organic (decomposing other organic substances such as eating meat and vegetables) or non-organic (such as light).
