Food chains are numerous branches that intersect with each other and form trophic points. There are grazing and remote food chains in nature. The former is otherwise called “chains to eat,” and the latter “chains of decomposition.”
Trophic food chains in nature
One of the critical concepts needed to understand nature’s life is the concept of the “trophic chain.” you can view it in a simplified, general way: plants – herbivores – predators, but in nature, food chains are much more branched and complex.
Energy and matter are transported along the chains of the food chain, up to 90% of which are lost when moving from one level to another. For this reason, there are usually 3 to 5 links in a chain.
Trophic chains are included in the general cycle of substances in nature. Because the actual connection in the ecosystem is entirely rash, for example, many animals, including humans, feed on plants, herbivores and predators, the food chains always intersect and form food webs.
Types of food chains
Usually, trophic chains are divided into pastures and remote. Both they and others function equally in nature.
Grazing chamber chains are related groups of organisms that differ in feeding, but individual links are joined by “eat” eating relationships.
The simplest example of a food chain is: cereal – mouse – fox; or grass deer is a wolf.
Detrital food webs represent the interplay of dead herbivores, carnivores and dead plant substances with detritus. Detritus is a common name for various groups of microorganisms and products of the activity of those involved in the decomposition of plant and animal residues. These are fungi and bacteria (decomposers).
There is also a food chain that links decomposition and predators: Detritus – (earthworm) – predator (thrush) – predator (hawk).
In nature, food chains are not stationary; they are strongly differentiated and intersect to form so-called trophic levels. For example, in the “grass-herbivore” system, the trophic level contains many species of plants that this animal eats, and the “herbivore” has many species of herbivores.
Trophic stages form a food pyramid (ecological pyramid), in which phases, where energy is transferred from detritus to producers (plants, algae), are shown with a diagram. From them to the primary consumer (herbivore). From them to side effects (carnivores) and to university users (predators that eat predators and parasites)
