Question on: JAMB Biology - 1999
The modes of nutrition in Nitrobacter, Ascaris and Homo sapiens respectively are
A
photosynthetic , parasitic and holozoic
B
chemosynthetic, parasitic and holozoic
C
photosynthetic, parasitic and heterophytic
D
chemosynthetic, holophytic and holozoic
Ask EduPadi AI for a detailed answer
Correct Option: B
Here's the breakdown of the modes of nutrition for each organism:
- Nitrobacter: This is a bacterium that obtains energy through chemosynthesis. It oxidizes inorganic substances (like ammonia) to create energy.
- Ascaris: This is a parasitic roundworm. It obtains nutrients by living within a host and absorbing digested food.
- Homo sapiens: Humans are holozoic, meaning they ingest complex organic food and break it down through digestion.
