Trophic Ecology is responsible for studying energy and food flows in ecosystems. Materials in the form of waste, living or processed products of one level, are actually resources for another organic level of complexity, whether microorganism, plant or animal. At the same time, the waste of these are trophic resources for other levels, giving rise to a food chain in which the immediate principles pass from one to another, from primary and secondary producers to consumers, also primary and secondary; and finally decomposers defined equally as primary and secondary. The decomposers simplify the products and start the cycle again. In this way, nature forms a system which self-stabilizes, producing and recovering materials consumed and used by a living network of great complexity.
Trophic ecology has great significance in the controlled cultivation of worms. In this ecosystem coexist from bacteria and fungi to insects, crustaceans and other worms for not mentioning undesirable neighbors. All these organisms contribute food principles and at the same time their wastes are trophic resources for other groups. The end result is obtaining a substrate very similar to that observed in a tropical forest, a climax soil.
This means that a well-stabilized earthworm cultivation, offers economic opportunities to the farmer, by obtaining a high-performance biological fertilizer, whose fundamental limiting factor lies in the domain of knowledge about soil characteristics and its compatibility with climax microorganisms. A soil dedicated to olive cultivation is not the same as that used for strawberries. Even the soil of an extensive olive cultivation is not the same as in ecological. The needs are double, the soil must maintain its original characteristics and, at the same time, a crop whose objective is to produce to the maximum in a stable and ecologically sustainable environment.
And here again nature offers economic opportunities, since the materials produced by earthworms are biofertilizers that take advantage of technologies combined with a good mastery of knowledge, something that is not always available. As a by-product, but in high demand, it is the large mass of living protein that bacteria, fungi, insects and the same worms represent, which can be used to feed other cultured organisms such as fish, farm animals, caged animals, and even produce food boosters for humans.
There is no doubt that vermiculture is a great example of what trophic ecology means and the economic and ecological advantages of the ecosystem represented by a worm cultivation.
