The compost cycle: from food scraps to fertile soil and back to food.

The image illustrates the compost process, a natural cycle that turns organic waste into nutrient-rich soil. Let's go through each step in order and explain how it works.

🔁 Compost Process (Step-by-Step Explanation)

#### 1. Scraps
- What happens?
Food scraps like fruit peels, vegetable trimmings, and leftover food are collected in a bin or container.
- Why is this important?
These scraps are organic materials that can decompose naturally. They are the starting point of the composting cycle.

#### 2. Compost
- What happens?
The food scraps are placed into a compost bin or pile. Over time, microorganisms (like bacteria and fungi), worms, and other decomposers break down the scraps into simpler substances.
- Key elements needed:
- Moisture
- Oxygen (aeration)
- A mix of "greens" (nitrogen-rich materials like food scraps) and "browns" (carbon-rich materials like dry leaves)
- Result:
After several weeks or months, the scraps turn into dark, crumbly material called compost.

#### 3. Fertilizer
- What happens?
The finished compost is used as fertilizer for plants. It enriches the soil with essential nutrients like nitrogen, phosphorus, and potassium.
- Benefits:
Improves soil structure, retains moisture, and supports healthy plant growth without using chemical fertilizers.

#### 4. Grow
- What happens?
Plants are grown in the nutrient-rich soil enriched by compost. The plants thrive because they receive vital nutrients from the compost.
- Examples shown:
Carrots, radishes, and leafy greens growing in the soil.

#### 5. Food
- What happens?
The grown vegetables and fruits are harvested and become food for people or animals.
- Cycle completes:
When we eat this food and discard the scraps, we return to Step 1 — beginning the compost cycle again.

🔄 Summary of the Cycle:

1. Scraps →
2. Compost →
3. Fertilizer →
4. Grow →
5. Food → Back to Scraps

This creates a closed-loop system where waste is recycled into valuable resources, reducing landfill waste and promoting sustainable gardening.
