4. Draw a mind map that contains the main points and important supporting details from the extract. You probably have some idea as to what Biology is. It is the study of animals and plants. Biology includes all that is known about any living thing, any plant or animal of the past or present. But Biology is more than mere accumulated knowledge of the individual kinds of plants and animals. The known facts about particular kinds of living things are used to discover the great principles and laws that govern all life. Biology sees life as a whole as well as living thing one by one. From this point of view, biology may be defined as the science of life. Biology is important to all mankind because it helps to solve a variety of problems. The knowledge that has enabled us to increase our food supply and to control plant diseases and pests comes from Biology. The improved methods of growing plants and the production of new varieties of plants are possible because of the ever-growing science of living things. Those who raise cattle and poultry to supply our demand for meat, milk and eggs find Biology important in many ways. Life in a city like Mumbai would be rather difficult without the services of Biologists. Milk and water must be kept from spreading diseases. Food must be inspected. Sewage is properly disposed off. Contagious diseases must be kept from spreading. Citizens must be treated so that they will not contact small pox, diphtheria, typhoid, rabies and many other preventable diseases. Every person who lives in a city depends on Biology for continued good health. Dentists, druggists, doctors, nurses, museum workers, zoo keepers all these use the findings of Biology in their everyday work.
