Biological Knowledge in Our Lives
Elnara Taghiyeva 
Abstract. Life on Earth cannot be imagined without living organisms. Biology is the science that studies organisms possessing all the characteristics of life. Living organisms are mainly classified into four major kingdoms: plants, bacteria, fungi, and animals. Viruses, however, are acellular forms of life and can reproduce only by entering the cells of other organisms. Various methods are used to study living organisms, including observation, experimentation, measurement, and microscopy. In addition, to facilitate their study, biologists classify organisms into groups based on common characteristics. In modern systematics, the origin of organisms, their structural features, and their evolutionary relationships are taken into account. Living organisms can be found on land, in water, in the air, and inside the bodies of other organisms. Within the biosphere, which is a complex system, the circulation of matter and energy occurs continuously. As a result of human activities, nature is sometimes exposed to strong negative impacts, and waste is generated daily in industrial and household activities. This waste is one of the main sources of environmental pollution and contributes to the disruption of ecological balance. To prevent this, recycling, more efficient use of natural resources, and environmental protection measures are essential factors.
