Rule of the Ecological Pyramid: transfer of energy from one trophic level to another with a decrease in energy by 10%.
There are a pyramid of numbers, reflecting the number of individuals in each link of the food chain, a biomass pyramid – the amount of organic matter synthesized at each level, an energy pyramid – the amount of energy in food. All of them have the same orientation, differing in the absolute value of digital values.
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.
