D.	Plasmodium	iv.	Switching between photosynthetic and heterotrophic mode

Choose the correct answer from the options given below :

• A. A-III, B-IV, C-II, D-I
• B. A-IV, B-II, C-I, D-III
• C. A-IV, B-III, C-II, D-I
• D. A-IV, B-II, С-III, D-I

Answer 1

The Correct Option is C

To solve this question, we need to match each organism from List I with its corresponding mode of nutrition from List II. Let's go through each organism and understand its nutrition mode: 

1. Euglenoid: Euglenoids are unique in that they can switch between photosynthetic and heterotrophic modes depending on the availability of light. When light is available, they become photosynthetic, and in the absence of light, they can act as heterotrophs, consuming organic matter. This mode is best described as "switching between photosynthetic and heterotrophic mode."
2. Dinoflagellate: Most dinoflagellates are photosynthetic organisms. They possess chlorophyll and carry out photosynthesis, which makes their mode of nutrition predominantly photosynthetic.
3. Slime mould: Slime moulds are saprophytic, meaning they obtain nutrients by breaking down organic matter. They feed on decaying vegetation and are often found on forest floors.
4. Plasmodium: Plasmodium is a parasitic organism. It is known for causing malaria in humans by parasitizing red blood cells. Thus, its mode of nutrition is parasitic.

Based on the above explanations, the correct matching is:

A.	Euglenoid	iv.	Switching between photosynthetic and heterotrophic mode
B.	Dinoflagellate	iii.	Photosynthetic
C.	Slime mould	ii.	Saprophytic
D.	Plasmodium	i.	Parasitic

Thus, the correct answer is: A-IV, B-III, C-II, D-I.
