At the same time, only photoautotrophic organisms can carry out photosynthesis, while chemoautotrophic organisms cannot carry out photosynthesis.
Of course, there are exceptions to everything. For example, mistletoe in plants has leaves, which can carry out photosynthesis, but mainly absorbs nutrients from the vascular tissues of the host plants, and belongs to heterotrophs. There are also insectivorous plants such as pitcher plants and sundew, which are not completely photoautotrophic organisms. Another example is the euglena, which can use chloroplasts in the body to obtain nutrients through photosynthesis, and can also absorb organic matter dissolved in water through the body surface. It is a creature between animals and plants.
