Answer
Factor 1: Temperature
I used a digital thermometer to measure the temperature at various locations within the ecosystem at different times of the day to find averages and fluctuations.
Factor 2: Soil pH
I tested the soil pH using a soil testing kit, collecting samples from several areas and following the instructions to get accurate readings.
Factor 3: Moisture levels
I used a moisture meter to determine the water content in the soil by inserting the probe into the ground at different spot.

Answer
The webbed feet of the Green Frog allow it to swim efficiently, making it easier to escape from predators and catch prey in the water. This adaptation enhances its chances of survival in an aquatic environment.
