Wildlife is diverse, it is very difficult to study it. Therefore, at certain stages of the formation of biology, knowledge became more and more, and different directions of knowledge were separated into separate sciences, for example, the science of plants – botany, the science of animals – zoology. Each of these sciences has its own objects, objects of research, but this does not mean that such sciences are isolated, they all study living systems that obey the unified laws, theories and phenomena.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
