Animals need to do this to get energy for survival, and all kinds of animals can eat it.

Insectivorous plants are very special. They can not only carry out photosynthesis, but also digest insects. Autotrophic and heterotrophic.

There is also a special kind, that is, mutual benefit, that is, two creatures live together, which is beneficial to each other. After separation, they can't live independently. Lichens, for example, are living organisms of fungi and algae. Lichens absorb nutrients through fungal mycelium and produce organic matter through the photosynthesis of algae plants. Fungi and algae in lichens cannot live independently if they are separated. Another example is the relationship between termites and intestinal flagellates, which is also mutually beneficial.
