Question

Which of the following groups contains only easily biodegradable items? (This question has multiple correct options)
A. Grass, flower and leather
B. Grass, wood and plastic
C. Fruits, peel cake and lime juice
D. Cake, wood and grass

Answer 1

Hint:- To approach this question, we need to know what biodegradable materials are and why they are used so widely nowadays.

Complete step-by-step solution:- Biodegradable items are the ones that can easily be degraded by nature itself (by the action of microorganisms).
Biodegradable items are least harmful to our nature as they do not leave any residue behind on being degraded.
OPTION (A) CORRECT
All the plants and animal’s parts are biodegradable because they can easily be decomposed by the natural enzymes.
Grass and flower are plant/plant parts and leather is the animal constituent. Thus, all these are biodegradable.
OPTION (B) INCORRECT
In this option, Grass and wood are biodegradable but plastic is not. Plastic can only be degraded by inorganic acids and leaves residue behind on decomposition.
OPTION (C) CORRECT
Fruits, peel cake and lime juice are biodegradable as all these can be degraded by the action of microorganisms.
OPTION (D) CORRECT
Cattle dung (Cake) is utilized in the mineral cycle. Wood is also biodegradable though it would take time to get degraded due to less water content. Grasses again fall in the former category.

Note:-
We know that the earth and its environment has been constantly degraded by anthropogenic actions i.e. human actions, so in order for our future generation to lead better healthy life, we need to take the steps that cause least harm to our environment now.
Our government has also been focusing on the use of biodegradable materials and renewable sources of energy so that we can limit the harm to the environment.
