Question

Case: Neena was writing a project report on modes of nutrition in different organisms. Heterotrophic organisms display three modes of nutrition i.e., saprophytic, parasitic and holozoic. In the holozoic mode of nutrition, a study on the digestive system of different animals showed that the length of the food pipe or oesophagus in different animals are different. The study showed that herbivores have a longer small intestine as compared to carnivores.
Help Neena to complete her report by answering the following question:

In which of the following groups of organisms food material is broken outside the body and then absorbed?

• A. Mushroom, green plants, amoeba
• B. Yeast, mushroom, bread moulds
• C. Paramecium, amoeba, cuscuta
• D. Cuscuta, lice, tapeworm

Answer 1

The correct option is B Yeast, mushroom, bread moulds

The mode of nutrition in which food is broken outside the body and then absorbed is known as saprotrophic nutrition and can be observed in fungi like yeast, mushroom and bread moulds.
