The transformation of energy in an ecosystem is somewhat different than the conversion of substances. The flow of solar energy entering the ecosystem, as it were, is divided into two channels – pasture and detrital. In each of them, energy is spent on maintaining the vital activity of organisms. The loss of energy in food chains can only be compensated for by the addition of new portions of solar energy or finished organic matter (feed energy). Therefore, in the ecosystem there cannot be a cycle of energy similar to a cycle of substances.
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.
