Which example describes an abiotic factor interacting with a biotic factor?

1. High water temperatures decrease oxygen concentration in the water.

2.Tropical fish need warm water to survive.

3.Small fish are food for larger fish.

4.More light increases the water temperature.

2.Tropical fish need warm water to survive.

Explanation:

The first option describes a relationship between two abiotic (non-living) factors i.e. the effect of high temperature on the oxygen concentration of water.Option 3 describes the relationship between two biotic (living) factors i.e. the smaller fish is prey for the larger fish.Option 4 again describes the relationship between two abiotic factors i.e. the effect of increase in light on water temperature.Therefore, the option 2 is the correct one as it describes relationship between tropical fish (biotic factor) and water temperature (abiotic factor)
