Question

Ethan made the following observations after 10 days of the above experiment: Plants in both locations were filled with 50 mL of water on Day 1 of the 10-day experiment. After 10 days, the cups in location 1 had approximately 30 mL in them. The cups in location 2 had approximately 18 mL in them. What could possibly explain the differences in the water in the cups in the two locations after 10 days?

a) Variation in sunlight exposure
b) Difference in soil quality
c) Difference in watering frequency
d) Difference in plant species

Answer 1

The water differences in the cups in the two locations after 10 days may be explained by variation in sunlight exposure, difference in soil quality, and difference in watering frequency.

Step-by-step explanation:

The differences in the water in the cups in the two locations after 10 days could be explained by variation in sunlight exposure, difference in soil quality, and difference in watering frequency.

Plants require sunlight for photosynthesis, which is the process of converting sunlight into energy. Variation in sunlight exposure can affect the rate of photosynthesis and, consequently, the amount of water used by the plants.

The quality of the soil can also impact water retention. Some soils have better drainage and may retain less water, resulting in faster evaporation and lower water levels in the cups.

Lastly, the watering frequency can affect the water levels in the cups. If the plants in location 1 were watered less frequently than those in location 2, it could explain why location 1 had less water in the cups after 10 days.
