The correct answer is Option (3) -A-4,B-3,C-1,D-2
Column I (Components of ecosystem)
|
Column II (Feeding habits)
|
| A. Scavengers |
4. Consumers of dead bodies |
| B. Parasites |
3. Consumers that feed on a small part of a living being |
| C. Producers |
1. Autotrophs |
| D. Phagotrophs |
2. Heterotrophs |
A. Scavengers → 4. Consumers of dead bodies
Explanation: Scavengers feed on dead organisms. They play a vital role in breaking down organic matter.
B. Parasites → 3. Consumers that feed on a small part of a living being
Explanation: Parasites obtain nutrients from a host organism, usually feeding on parts without necessarily killing it.
C. Producers → 1. Autotrophs
Explanation: Producers, like plants, are autotrophs that make their own food through photosynthesis or chemosynthesis.
D. Phagotrophs → 2. Heterotrophs
Explanation: Phagotrophs are heterotrophs that feed by engulfing or ingesting solid food particles, such as certain protozoa and animals. They obtain their nutrients by engulfing or ingesting solid food particles. They feed on other organisms or organic matter, which is then digested internally. |
