Question

Case: Neena was writing a project report on nutrition in different organisms. 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:

Which of the following organisms have the same mode of nutrition as the animals including humans?

• A. Plants
• B. Fungi
• C. Amoeba
• D. All of the above

Answer 1

The correct option is C Amoeba

All green plants have an autotrophic mode of nutrition. They prepare their own food by utilising solar energy, water, and carbon dioxide through the process of photosynthesis. Heterotrophic nutrition is the mode of nutrition where the organism is unable to prepare its own food and hence, depends upon plants or other organisms for nutrition. It is of three types, saprophytic, parasitic and holozoic. Fungi obtain food from dead and decaying substances and hence follow a saprophytic mode of nutrition, whereas amoeba and other animals including humans follow a holozoic mode of nutrition
