| List - I Organisms | List – II Mode of Nutrition | ||
| A. | Euglenoid | i. | Parasitic |
| B. | Dinoflagellate | ii. | Saprophytic |
| C. | Slime mould | iii. | Photosynthetic |
| D. | Plasmodium | iv. | Switching between photosynthetic and heterotrophic mode |
The correct matches are:
Euglenoids can switch between photosynthetic (autotrophic) and heterotrophic modes of nutrition. Thus, A-IV.
Dinoflagellates are mostly photosynthetic. Thus, B-III.
Slime moulds are saprophytic (feed on dead organic matter). Thus, C-II.
Plasmodium is parasitic, obtaining nutrients from a host. Thus, D-I.
Therefore, the correct option is (3): A-IV, B-III, C-II, D-I.
