Q. What is biodiversity? Why is it important in our lives? (5marks) (2019)
-> Bio- diversity refers to variety and variability of plant, animal and human life on earth. Biodiversity is very important in our lives because all the plants, animals and human life on earth survive depending upon one another. At the same time among plants, animals there are different species which is very important. Similarly, we eat varieties of food also. We cannot eat the same dish every day. In our meal one item is not sufficient. Various items constitute the meal. Likewise, in India we enjoy the taste of seven hundred varieties of mangoes through the few months of summer.
Q. Do you think the writers’ comparison of the ship losing nuts to the loss of biodiversity is apt? Why do they make this comparison? (5marks) (2016)
-> The writer’s comparison of the ship losing nuts to the loss of biodiversity is doubtlessly apt. Because the ship that is losing one nut at a time and gradually going to sink and the same is the case of losing biodiversity. We are losing the species and genes that keep the earth ‘afloat’ stepwise. The line of decline is increasing. If we are unable to check this line the earth will also sink. Already signs of this alarming condition are manifested by a series of global changes in climate, hydrological patterns and other ecological functions that we all survive on. And by the collapse of global fisheries, the desertification of tens of millions of hectares of one productive land, the loss of soil nutrition and so on.
Both scenes are likewise the same and the comparison has perfectly matched.
