Question
In this type of heterotrophic nutrition, food is obtained by absorption...
Correct Answer
Option B is the correct answer.
Detailed Explanation
Saprotrophic nutrition involves organisms (like fungi and some bacteria) that secrete digestive enzymes onto dead or decaying organic matter and then absorb the digested nutrients. Parasitic organisms live on or in a host and obtain nutrients from it, often harming the host. Holozoic nutrition involves ingesting solid food particles, and mixotrophic organisms combine different nutritional strategies.
Hint
Think about organisms that live on decaying matter and how they obtain nutrients without ingesting solid food.
