Which of the following is not an abiotic factor?
- (a)Temperature
- (b)Humidity
- (c)Algae
- (d)Moisture
Answer
C
Why
Correct — C, Algae. Abiotic factors are the non-living, physical conditions of an environment. Temperature, humidity and moisture are all such physical conditions, but algae are living plant-like organisms, so they are a biotic factor and are the odd one out.
Why the others are wrong
- (a)Temperature — Temperature is a non-living, physical condition of the environment, so it is an abiotic factor and does not fit the 'not abiotic' answer.
- (b)Humidity — Humidity is a non-living, physical condition of the air, so it is an abiotic factor, not the odd one out.
- (d)Moisture — Moisture is a non-living, physical condition, so it too is an abiotic factor and is not the exception the question wants.
Concept
A reading-comprehension item testing the split between non-living (abiotic) conditions and a living (biotic) organism such as algae.
