the color of the water the number of predators the temperature of the water the populations of producers
I gave my students this multiple choice question: Which is an abiotic factor that most limits the number of frogs living in a pond?

Only one answer is correct among these 4 choices:
- the color of the water
- the number of predators
- the temperature of the water
- the populations of producers

Could you tell me which one is correct?

the temperature of the water
