For example, parasitic plants are both autotrophic and heterotrophic, such as dodder and mistletoe.

In addition, there are pitcher plants and flycatchers, both autotrophic and heterotrophic;

Not all animals are heterotrophic.

For example, some protozoa also contain pigments, which can independently synthesize organic matter;

Difference: mainly from the cell morphology, the proportion of eukaryotes and prokaryotes is mainly whether there is a formed nucleus, animals and plants are eukaryotes, and the main difference between animal and plant cells is whether there are vacuoles and cell walls.
