1. Herbivores : Primary consumers
Correct. Herbivores feed mainly on plants and are primary consumers. Examples include cows and rabbits.
2. Wolves : Secondary consumers
Correct. Wolves feed on primary consumers and are considered secondary consumers.
3. Algae : Primary producers
Correct. Algae, like green plants, perform photosynthesis and are primary producers in aquatic ecosystems.
4. Earthworm : Macro consumers
Incorrect. Earthworms are not macro consumers; they are detritivores, which helps in the decomposition of organic matter. They are considered micro consumers as they decompose dead organic substances.
Thus, three pairs are correctly matched.

Understanding the Pairs
In ecology, organisms are classified based on their roles in the food chain. Let’s analyze each pair to determine their correctness.
1. Herbivores : Primary Consumers
- This pair is correctly matched.
- Herbivores, like deer and rabbits, feed on plants and are classified as primary consumers in the food chain.
2. Wolves : Secondary Consumers
- This pair is also correctly matched.
- Wolves are carnivores that prey on herbivores, thus they are considered secondary consumers.
3. Algae : Primary Producers
- This pair is correctly matched as well.
- Algae perform photosynthesis and produce energy, making them primary producers in aquatic ecosystems.
4. Earthworm : Macro Consumers
- This pair is not correctly matched.
- Earthworms are decomposers or detritivores, breaking down organic matter rather than being classified as macro consumers, which typically refers to larger organisms that consume other organisms.
Conclusion
- Out of the four pairs, three are correctly matched:
- Herbivores are primary consumers.
- Wolves are secondary consumers.
- Algae are primary producers.
- Only the earthworm pair is incorrect.
Thus, the correct answer is option 'C': only three pairs are correctly matched.
