Pigeon odour is released from the water bloom of:
Correct answer: D. Cyanobacteria Algae ponds
- A. Slime mold
- B. Water mold
- C. Cyanobacteria
- D. Cyanobacteria Algae ponds
Explanation
The correct answer is Cyanobacteria Algae ponds. Cyanobacteria, often called blue-green algae, can form dense blooms in water, releasing odors due to the organic compounds they produce. These blooms can make the water smell unpleasant and affect its quality. Slime molds and water molds, while they exist in moist environments, do not typically contribute to offensive odors in water bodies. Cyanobacteria, due to their ability to proliferate rapidly in nutrient-rich waters, are the main culprits behind such issues.
