Practice questions testing deep understanding of biodegradable vs non-biodegradable waste.
Q1. A family decides to bury all their household waste in their backyard to avoid paying for garbage collection. Six months later, they dig up the area. They find that the vegetable peels, paper, and cotton rags have completely disappeared, but the plastic bags, glass bottles, and aluminum foil look exactly the same. Explain this observation using biological terminology.
Q2. Assertion (A): Electronic waste (e-waste) from old computers and phones should not be thrown into regular municipal landfills. Reason (R): E-waste contains highly toxic heavy metals like lead, mercury, and cadmium, which can leach into the soil and severely contaminate the groundwater.
