Both Alex and Jamie used identical setups for their seed germination experiment. Each student spread an equal number of seeds on a paper towel, added the same measured amount of water, ensured that air was present in the plastic bag, and sealed it tightly. They then taped their plastic bags onto a window that receives sunlight throughout the day, providing the necessary light for the seeds to germinate.

Jamie had two identical potted plants that were the same species and size. She decided to care for them a bit differently by placing one on her sunny porch and the other in a shady corner of her backyard. Both plants received the same amount of water and care each day. After several weeks, Jamie noticed that the plant on the sunny porch had grown taller, developed stronger stems, and boasted a rich green color in its leaves. In contrast, the plant kept in the shade stayed smaller and its leaves looked pale. This experiment showed that sunlight plays a key role in helping plants grow strong and healthy.
Which of the following claims best describes what happened with the potted plants?
A. The plant that received more sunlight grew better because sunlight helps plants make food through photosynthesis.
B. Both plants grew equally because they received the same amount of water.
C. The plant in the shade grew better because it was protected from too much sun.
D. The plants did not change because sunlight has no effect on plant growth.
A. The plant that received more sunlight grew better because sunlight helps plants make food through photosynthesis.

Earthworms are vital for soil health because they recycle nutrients by breaking down decaying plant material. Instead of using sunlight to produce energy like plants, earthworms ingest soil that contains fallen leaves, dead roots, and other organic debris. Within their digestive system, enzymes and beneficial bacteria help decompose this material, releasing essential nutrients such as nitrogen and phosphorus that support their growth and, in turn, enrich the soil with their castings.
Question:
How do earthworms primarily obtain the nutrients they need for growth?
A. Through photosynthesis
B. By consuming soil rich in decomposing organic matter
C. By absorbing nutrients directly from the air
D. By hunting small insects
B. By consuming soil rich in decomposing organic matter

Worms, especially earthworms, get their nutrients by eating soil that is rich in decomposing organic matter. As they burrow through the ground, they consume tiny bits of decaying leaves, dead roots, and other organic materials. Inside their long, tube-like bodies, worms use their digestive systems, along with helpful bacteria, to break down this material and absorb essential nutrients such as nitrogen and carbon. The leftovers, known as castings, are excreted and help make the soil even more fertile, supporting new plant growth.
How do worms primarily get their nutrients?
A. Through photosynthesis
B. By eating soil with decomposing organic matter
C. By directly absorbing nutrients from the air
D. By catching and eating small insects
B. By eating soil with decomposing organic matter
