TASK 1:
Question: The diagrams below show how to recycle organic waste to produce garden fertilizer (compost).
ANSWER:
The given diagram illustrates the process of recycling organic waste in order to produce garden fertilizer, commonly known as compost.
Overall, the procedure involves five main stages, beginning with the preparation of a plastic container and the addition of organic waste materials, and culminating in the production of compost after six months. The process relies on natural decomposition aided by air, water, nitrogen, and heat.
To begin with, a two-cubic-metre plastic container is prepared with several small air holes on its sides. A 15-centimetre layer of waste materials, such as newspapers, grass, and food remains, is then placed inside the container. Following this, nitrogen and hot water are added to the mixture, which helps accelerate the decomposition process. At this stage, heat is generated within the container, contributing to the breakdown of the organic matter.
Over the course of six months, the combined effect of air circulation, moisture, and warmth allows the organic waste to decompose fully. Eventually, the mixture turns into nutrient-rich compost, which can be utilized as fertilizer in the garden. (174 words)
