Answer: Mushroom, yeast, mold
Step-by-step explanation:
These organism look like plants but they are not plants so they cannot make their own food by the help of the process known as photosynthesis.
They lack chlorophyll and cannot trap sunlight to convert it into chemical energy.
These organism are heterotroph and they feed on other organism for their food. Mushroom and mold feed on the host or dead and decaying matter for their food. Yeast also feed on sugars and starch for their food.
Hence, the correct answers are mushroom, yeast and mold.
