Use different examples, prove that any organism cannot live outside its usual habitat. What does the body get from the environment, what does it release into the environment?
Any living organism cannot live outside its environment. Equally impossible is the development of the organism outside the environment, outside the factors that influence it. A chicken egg can develop only at a certain temperature. The embryo of mammals, including humans, is very sensitive to the effects of adverse environmental factors; its development is affected by the substances that it receives with the mother’s blood. Organisms receive food, water, solar energy. All species are sensitive to carbon dioxide. Undigested food residues, urea and other metabolic products are isolated.
The influence of the environment on the body leads to changes in it, that is, to modification variability.
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.
