Answer 1

Correct Answer - b
Yeast, mushroom and bread mould are saprophytes They break down and convert complex organic molecules present in dead and dead and decaying matter into simpler substances outside their body. These simpler substances are then absorbed by them, (i.e., saprotrophic nutrition).
Green plants are authrophic (make their own food through photosynthesis).
Amoeba and Paramecium are holozoic (take solid or organic food and Cuscuta, lice, tapeworm are parasitic (live on food material obtained from the body of host).
