Solution 2

Biology is the branch of science dealing with the study of living organisms including their structure, evolution, growth and environment.
Biology is important in our daily life in the following ways:
(i) Food - Study of various food components helps in understanding balanced diet and its significance.  We get food directly or indirectly through agriculture, which is helped by the studies of different branches of Biology.
(ii) Health - Biology helps us to understand structure and functions of our various body parts as well the various diseases that we suffer from and their cure.
(iii) Agriculture - Biology helps us to increase the overall agricultural production by providing knowledge about new methods of farming, improved seed varieties and crop protection against many diseases.
(iv) Clothes - Materials for making clothes like wool, fur and silk are obtained from animals whereas cotton is obtained from plants. Biology deals with these animals and plants.
(v) Industry - Many industries are based on animal and plant products like leather, horn, shells, honey, wax, pearl, wood, rubber etc. Increased manufacture of these products can be achieved using the knowledge of Biology.
(vi) Human Diseases - Many animals cause and transmit diseases. Also many animals are used for testing new drugs before use on humans. The tremendous advances in human physiology, medicine and surgery have come from the study of zoology.
(vii) Aesthetic value - We keep many animals like birds, fishes and butterflies for entertainment and hobby. Visiting gardens and parks also gives us aesthetic pleasure. Biology helps in the study of these animals and plants to provide us better aesthetic value.
(viii) Improvement of domestic animals - Raising improved breeds of domestic animals gives better yields and this is made possible by zoology and genetics.
(ix) Space research - Biology helps in man's quest of knowing about extra terrestrial life.

Solution 4

Study of Biology is advantageous to us in many ways. These are:
(i) It helps us to understand ourselves better such as our body activities, our hereditary, our evolution, need for food, life and death etc.
(ii) It helps us to remain healthy and fit by knowing our body structure and functioning.
(iii) It tells us about the types of human diseases and their causes. It also helps in the prevention and cure of human diseases.
(iv) Biology ensures maximum utilization of resources available to us such as increasing crop production, improving breeds of useful animals, using microbes in food, industry and medicine, curing diseases and overall improving the quality of life.
(v) It informs us about the negative consequences of excessive use of fertilizers and pesticides like degradation of soil quality and harming living beings including humans through food chains.
(vi) Biology tells us about the problems of deforestation and its effects on the environment.
(vii) It makes us aware about the causes and harmful effects of pollution and ways of controlling it.
(viii) Biology stresses the need for conservation of natural resources, so that they are available to future generations.
(ix) It informs us about our responsibility towards other forms of life and our planet at large, for sustainable living.
(x) It makes us aware of the need to maintain the delicately balanced ecosystem containing various food chains and food webs.
(xi) Biology solves many problems facing mankind such as eradication of fatal diseases, decreasing environmental pollution, increasing food supply, recharging fresh water resources etc.
