The fall in the amount of energy during the transition from one trophic level to another (higher) determines the number of these levels and the ratio of predators to prey. It is estimated that about 10% (or slightly more) of the energy of the previous level is supplied to any given trophic level. Therefore, the total number of trophic levels is rarely more than four or six.
This phenomenon, depicted graphically, was called the ecological pyramid. There are a pyramid of numbers (individuals), a pyramid of biomass and a pyramid of energy.
The base of the pyramid is formed by producers (plants). Above them are consumers of the first order (herbivores). The next level is represented by second-order consumers (predators). And so on to the top of the pyramid, which is occupied by the largest predators. The height of the pyramid usually corresponds to the length of the food chain.
The biomass pyramid shows the ratio of the biomass of organisms of different trophic levels, depicted graphically in such a way that the length or area of the rectangle corresponding to a specific trophic level is proportional to its biomass
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.
