Question

ln which of the following groups of organisms, food material is broken down outside the body and absorbed ?​

Answer 1

The green plant is photoautotrophs that synthesise food material from simple inorganic compounds like water and carbon dioxide in the presence of sunlight.  

Nutrition in Amoeba and Paramecium is holozoic. Thus, solid food particles are ingested which are then acted upon by enzymes and digested. Cuscuta, lice, and tapeworm are parasites with the heterotrophic nutritional mode. Yeast, mushroom and bread mould have a saprophytic mode of nutrition which is chemoheterotrophic in nature. They break down complex organic substances by secreting digestive enzymes outside their body and absorb simple molecules as nutrients. So, the correct answer is option B.
