Completed Passage:
Microscopic creatures called
decomposers break down dead plants and return their nutrients to the soil. Farmers and gardeners can recycle nutrients by
composting, which means combining
brown (a color) plant materials in a pile with water.
Heat from the sun raises the temperature in the pile, so everything breaks down.

✔ Explanation of Each Answer:
1.
“decomposers”
→ The first paragraph says: *“microscopic creatures called decomposers break it down and return its nutrients to the soil.”*
So, “decomposers” is the exact word used in the text to describe these tiny organisms that break down dead matter.
2.
“composting”
→ The passage explains: *“To keep from wasting this precious resource, many people with backyard gardens also compost.”*
And later: *“Composting means combining brown plant materials…”*
So, “composting” is the process farmers and gardeners use to recycle nutrients.
3.
“brown”
→ The text clearly states: *“Composting means combining brown plant materials like straw, shredded wood, and dead leaves…”*
This directly tells us the color associated with those materials — “brown.”
4.
“Heat”
→ The passage says: *“Heat from the sun raises the temperature in the pile, encouraging decomposers and helping it all to break down.”*
So, “Heat” is what comes from the sun to speed up decomposition.

🌱 Why This Matters:
This passage teaches how nature recycles nutrients — when plants die, decomposers turn them into soil food. But modern waste habits (like throwing food scraps in plastic bags) break this cycle. Composting lets humans help nature by recreating that recycling system — using brown and green materials, water, and heat to make “garden gold” for new plants!
