Food chain

 Food chain

1) The flow of energy and carbon in the form of food from one nutritional level of organisms to another. Nutritional trophic levels are based on the source from which the organisms feed. The first link in the food chain is formed by green plants, which are the first (primary) producers in nature. This is followed by herbivores, carnivores from herbivores, meat and grass gluttons, meat and other creatures, including man, who eats meat and grass from gluttons. Thus, matter and energy are transported from one nutritional level to another. The transport of substances from one trophic level to another is around 10%.

2) Linear model in the form of rings in a chain of producers, consumers and separators in terms of food intake relationships.
