The correct answer is C.Temperature of the water.

In a pond ecosystem, the temperature of the water is a critical abiotic factor that affects the survival of aquatic organisms. Water temperature influences metabolic rates, reproduction, oxygen solubility, and the overall health of the organisms living in the pond. Different species have specific temperature ranges within which they can thrive, so any significant changes in water temperature can impact the ecosystem's balance.

Let's clarify the other options:

A.Availability of prey is a biotic factor because it involves living organisms and is important for predators in the ecosystem. ...
