Which of the following is an abiotic factor influencing a tidal rock pool ecosystem along the Wellington coast?
Answer and explanation
Correct answer: A. Water temperature, salinity, and dissolved oxygen levels in the rock pool
- Step 1: Abiotic factors are non-living physical and chemical components of an environment (temperature, salinity, light, pH, oxygen). Step 2. Biotic factors involve interactions between living organisms (predation, competition, parasitism). Answer: Water temperature, salinity, and dissolved oxygen levels in the rock pool. Why not the others: Temperature and salinity are classic abiotic variables.
