Back Question - Our Environment | NCERT | Science | Class 10
Which of the following groups contain only biodegradable items?
(a) Grass, flowers and leather
(b) Grass, wood and plastic
(c) Fruit-peels, cake and lime-juice
(d) Cake, wood and grass
Biodegradable items are those that can be broken down naturally by microorganisms into simpler, non-toxic substances, returning nutrients back into the environment. Now, let's evaluate each option:
(a) Grass, flowers, and leather: All these items can be broken down by microorganisms. Leather, being an animal product, is biodegradable though it takes longer to decompose compared to plant material.
(b) Grass, wood, and plastic: Grass and wood are biodegradable. However, most plastics are not biodegradable as they are synthetic materials made from petroleum and can take hundreds to thousands of years to decompose in natural environments.
(c) Fruit-peels, cake, and lime-juice: All these items are biodegradable. Fruit peels and cake are organic matter that can decompose quickly. Lime juice, being a liquid, naturally integrates back into the environment.
(d) Cake, wood, and grass: Similar to option (c), all these items are biodegradable. Cake and grass will decompose rapidly, and wood, while taking longer, is also biodegradable.
Answer: Options (a), (c), and (d) contain only biodegradable items. Option (b) includes plastic, which is not biodegradable, making it the incorrect choice in this context.
Which of the following constitute a food-chain?
(a) Grass, wheat and mango
(b) Grass, goat and human
(c) Goat, cow and elephant
(d) Grass, fish and goat
