Nina is learning about plants in school. Her teacher gives her group a stack of cards that list things that plants might need to make their own food. Written on the cards are the words “water,” “soil,” “sunlight,” and “air.” One card does not belong. Which of the cards should Nina’s group take out of the pile?
A air
B soil
C sunlight
D water
The card that Nina’s group should take out of the pile is B soil.
Explanation: While all the other cards (air, sunlight, and water) are essential for the process of photosynthesis, which is how plants make their food, soil is not directly involved in the food-making process. Soil is important for plant growth and provides nutrients, but it does not play a role in the actual production of food like the other elements do.
