Answer: In saprotrophs, food is digested (c) outside the cells.
Explanation:
Food is digested outside in organisms like bread mould, yeast, mushroom, etc.
More:
- There are basically 4 types of heterotrophic nutrition seen in animals, viz. – holozoic, parasitic, saprotrophic, and symbiotic.
- In holozoic, nutrition is done by ingestion, digestion (digestive tract of GI tract in humans, vacuole in ameba), assimilation & excretion/egestion.
- Organisms who depend on hosts for food and make no food by them are called parasites. This nutrition is called parasitic nutrition. Ex : ticks, lice, amarbel, leeches, etc.
- Saprotrophs feed on dead and decaying matter. This nutrition is, therefore, called saprophytic nutrition.
- When two organisms are mutually depend for nutrition, this is called symbiotic nutrition.
PS: So, do plants & humans follow symbiotic nutrition/relationship?
No. They ain't in close association. It needs close association to do so.
