Q.9. Give reasons:
(1) It is important to
conserve the living components of the environment.
Answer: If the living components of the environment do not exist, then
the food chain and food web will not function. Some species will get extinct.
Living things were produced on earth many million years back. It is not
possible to get them back by man-made processes. If the balance in nature is
disturbed it will affect human beings too. Therefore, it is important to
conserve the living components of the environment.
(2) The numbers of wild
animals are falling day by day.
Answer: Due to human interventions, many food chains and food webs are
disturbed. Forests are cleared for making land available. Due to loss of
forest, wild animals are displaced. Due to climate change and global warming,
natural cycles are also disturbed causing survival of wild animals difficult.
Hunting and poaching of wild animals have also reduced their numbers
significantly. All these factors have led to fall in the number of wild
animals.
(3) (1) When there is an
epidemic of cholera, we should drink boiled water.
Answer: Germs of cholera spread through faeces of a patient. They pass
into water or food. If such contaminated water is used for drinking, others may
get the infection of cholera. Therefore, during epidemic of cholera, water
should be boiled. Boiling destroys the germs in the water and therefore we are
protected against the germs. In order to keep our health safe, we should drink
boiled water.
(4) We should not allow
puddles of water to stand in our surroundings.
Answer: Stagnant water of puddles is a breeding ground for mosquitoes.
Germs causing malaria are transmitted through mosquitoes’ bite from a patient
to other people. Epidemic of such diseases will spread if mosquitoes are
abundant. Therefore, to control infections of malaria and dengue we should
eradicate mosquitoes. Hence, we should not allow puddles of water to stand in
our surroundings.
