Plants in eukaryotes are basically autotrophic, which can be divided into chemoautotrophic and photosynthetic autotrophic, both of which are photosynthetic autotrophic.

The important structures of photosynthetic autotrophy are chlorophyll and some pigments, which are basically found in eukaryotic plants, so eukaryotic plants are basically autotrophic, with exceptions.

Heterotrophs in eukaryotes, except for green plants and most algae, ferns and mosses, are heterotrophs, and animals in natural eukaryotes are heterotrophs.
