What is Food Chain?
A food chain represents the flow of energy and nutrients among different organisms in an ecosystem. It tells us how energy and nutrients are transferred from one trophic level to another and how the organisms interact in an ecosystem. In a food chain, each organism represents a particular trophic level according to its food behavior.
- Producers are living organisms that produce their own food by utilizing solar energy through the photosynthesis process. For example, plants, green growth, etc.
- Consumers are living organisms that cannot produce their own food and obtain energy by consuming other organisms. For example, lions, tigers, wolves, foxes, etc.
- Decomposers are the organisms that breaks down dead organic matter and recycles nutrients back into the ecosystem. They are present at the last stage of the food chain, that breaks down waste and remains from all other trophic levels. For example, bacteria and fungi.
What is Food Chain?
Food chain represents the direction of the flow of energy and nutrients through an ecosystem. It consists of four main components producers, primary consumers, secondary consumers, and decomposers. Based on the primary source of energy there are two types of food chain: Grazing and the Detritus food chain. It makes us understand the interaction among the species, the interdependence of organisms in nature, and how energy is transferred from one level to the next, sustaining life within an ecosystem.
