Food chain: A cyclic relation between all the organisms of the world

Food chain and food webs or food networks describe the feeding relationships between species in a community. In alternative words, they show the transfer of minerals and energy from one species to a different at intervals in an ecosystem. An organism is connected to another organism for its supply of food energy in the process of a biomass transfer. Organisms are divided into organic process levels based on their distance with other organisms placed in the ecosystem. Primary producers, or autotrophs, are a species capable of manufacturing complicated organic substances from an energy supply and inorganic materials.

These organisms are generally photosynthetic plants, microorganisms or algae, however in exceptional cases, like the organisms from the bottom of sea vent food webs, the organisms can be chemotropic. All organisms that eat the autotrophs(self-nourishing) are referred to as heterotrophs. They get their energy by feeding the producers.

A food chain describes one pathway that energy and nutrients might follow in an ecosystem. There is one organism per tropic level, and tropic levels are therefore simply outlined. They sometimes begin with a primary producer and finish with a prime predator.

Organisms in food chains are classified into numerous classes or trophic levels. Roughly speaking, these levels are divided into: Producers or the primary organic process level, consumers constituting the second, third, and fourth organic process levels and decomposers.

The second organic process level consists of organisms that eat the producers. These are referred to as primary consumers, or herbivores. Deer, turtles, and plenty of forms of birds are herbivores. Secondary consumers eat the herbivores. Tertiary customers eat the secondary consumers.

The third level of consumers are carnivores or animals that eat other animals or omnivores that eat both plants and animals. Omnivores include human beings who consume many types of foods.

Decomposers are the final part of the food chains. Detritivores are organisms that eat non-living plants and animal remains. Decomposers like fungi and bacteria complete the food chain. They transform organic wastes, such as decaying plants, into inorganic materials, such as nutrient-rich soil by chemical synthesis of the minerals.
