Algae would generally NOT be found residing in which of the following?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. Dry stone.
Algae are simple, plant-like organisms that need moisture, sunlight, and nutrients to survive. Among the options, dry stone is the least likely place where algae would grow. This is because dry stones lack moisture, and their often hot surfaces make them unsuitable for algal survival. Algae thrive in damp or wet conditions, and without water, they cannot photosynthesize or reproduce effectively.
In contrast:
-
Soil: Algae can grow on moist soil surfaces, especially in humid environments. They help improve soil fertility by fixing nitrogen.
-
Fresh water: This is one of the most common habitats for algae. They float freely or attach to submerged surfaces in ponds, lakes, and rivers.
-
Wood: Algae can grow on damp wood, especially in shaded, humid areas such as forest logs or wet fences.
