पर्याय

• Mushroom, Green plants, Amoeba

• Yeast, Mushroom, Bread mould

• Paramecium, Amoeba, Cuscuta

• Cuscuta, Lice, Tapeworm

Answer 1

Yeast, Mushroom, Bread mould

Explanation:

Yeast, mushroom, and bread mould belong to the kingdom of Fungi and exhibit a saprophytic (or saprotrophic) mode of nutrition. Because they cannot ingest solid food directly, they secrete powerful digestive enzymes onto dead and decaying organic matter in their surroundings. These enzymes break down complex organic materials into simpler, soluble molecules outside of the body. Once digested externally, the fungi directly absorb the simple nutrients through their cell walls.
