Problem Analysis:
The task is a reading comprehension exercise based on the passage about "Garden Gold." The goal is to fill in the blanks using information from the text. Let's break it down step by step.
---
Passage Summary:
1.
Decomposers: Microscopic creatures that break down dead plants and return their nutrients to the soil.
2.
Modern Waste: In modern life, scraps from dead plants (fruits, vegetables, etc.) often end up in plastic bags, garbage cans, or landfills instead of returning to the soil.
3.
Composting: To recycle nutrients, many people use composting. Compost is made by combining brown plant materials (straw, shredded wood, dead leaves) with green materials (vegetable scraps) in a pile with water.
4.
Heat from the Sun: Heat from the sun raises the temperature in the compost pile, helping decomposers break everything down.
5.
Value of Compost: Compost is nutrient-dense and valuable for growing healthy plants, sometimes called "black gold."
