Question

the passage below describes an experiment. read the passage and then follow the instructions below. daniel planted one tomato plant in each of nine identical pots. he planted three plants in soil that had a ph of 5.0, three plants in soil that had a ph of 6.5, and three plants in soil that had a ph of 8.0. he placed all the pots in a section of his backyard that gets direct sunlight for six hours each day. he gave each tomato plant three cups of water per day. over the course of one month, daniel counted the number of tomatoes that each plant produced. identify the question that daniels experiment can best answer. do plants produce more tomatoes when they are given three or six cups of water per day? is the amount of time that tomato plants live affected by soil ph levels? do soil ph levels affect the number of tomatoes a tomato plant produces?

Explanation:

Daniel's experiment has different soil pH levels (5.0, 6.5, 8.0) as the variable. He keeps other factors like sunlight (six hours each day) and water (three cups per day) constant. He counts the number of tomatoes each plant produces. So, the experiment is designed to see the relationship between soil pH levels and the number of tomatoes produced.

Answer:

Do soil pH levels affect the number of tomatoes a tomato plant produces?
