Read the following story titled 'Eco-friendly Prithvi', and tick the most appropriate option(s) given in the brackets. Provide a suitable title of your choice for the story.
Prithvi is preparing a meal in the kitchen. He chops vegetables, peels potatoes, and cuts fruits (physical changes / chemical changes). He collects the seeds, fruits, and vegetable peels into a clay pot (physical change / chemical change). The fruits, vegetable peels, and other materials begin to decompose due to the action of bacteria and fungi, forming compost (physical change / chemical change). He decides to plant seeds in the compost and water them regularly. After a few days, he notices that the seeds begin to germinate and small plants start to grow, eventually blooming into colourful flowers (physical change / chemical change). His efforts are appreciated by all his family members.

Suggested title: "From Kitchen Waste to a Garden Bloom" (or "Prithvi's Compost Garden", "Nothing Wasted", etc.)
Filled-in story with correct options ticked:
- "He chops vegetables, peels potatoes, and cuts fruits" → physical changes (only size and shape change; vegetables and fruits remain the same substances).
- "He collects the seeds, fruits, and vegetable peels into a clay pot" → physical change (just moving things around; no substance is changed).
- "The fruits, vegetable peels, and other materials begin to decompose due to the action of bacteria and fungi, forming compost" → chemical change (bacteria and fungi break down the waste, producing new substances — humus, simpler nutrients).
- "The seeds begin to germinate and small plants start to grow, eventually blooming into colourful flowers" → chemical change (germination and growth involve countless chemical reactions; new tissues, leaves, and flowers are produced inside the plant).
