Food chain concept—While natural food webs are characterized by vast complexity, many food web studies simplify matters by grouping functionally similar organisms. When considered in energetic terms, organisms are often combined into trophic levels – groups of species that are thought of as comprising a single step in ecosystem energy transfer.
Food chains generally consist of three or four steps (three or four organisms) because after that the energy available for the next organism will be so small that it will be insufficient to sustain the life of that organism. There are, however, some food chains containing five steps (or five organisms) but there are rarely more than five steps ...

· Trophic level is the position within a food chain that is occupied by a group of organisms in an ecosystem. The classifiion of organisms into the different food chains is based on their feeding behavior. Trophic level is a step in the nutritive series of food chains which in some cases might form a complied path called a food web.
The HACCP team will identify the steps that will be taken to prevent potentially hazardous food from entering the food chain and the steps that are needed to correct the process. This usually includes identifiion of the problems and the steps taken to assure that the problem will not occur again. Principle 6 Verifiion
· Various steps in a food chain are known as trophic levels. The first trophic level is of producers. The second trophic level is of primary consumers also known as herbivores, third of carnivores, or secondary consumers, fourth is of tertiary consumers also known as top carnivores.
· In a food chain, there are four crucial members. There are the primary producers, primary consumers, secondary consumers and tertiary consumers.
· Creating a food web is a really great way to learn more about how organisms and animals live in their natural habitats. While a food chain shows how ecosystems function in a linear way, a food web is a more visual approach with multiple animals connected to one another. To .
Food Chain starts with plant because Plants are called producers and they are able to use light energy from the sun to produce food (sugar) from carbon dioxide and water. Animals cannot make their own food so they must eat plants and/or other animals.

The Carbon Cycle Step 4. The dead organisms (dead animals and plants) are eaten by decomposers in the ground. The carbon that was in their bodies is then returned to the atmosphere as carbon dioxide. In some circumstances the process of decomposition is prevented.
In addition, the flow diagram can include steps in the food chain which are before and after the processing that occurs in the establishment. The flow diagram need not be as complex as engineering ...
The purpose of this paper is to review the food supply chain management (FSCM) in terms of systems and implementations so that observations and lessons from this research could be useful for academia and industrial practitioners in the future.,A systematical and hierarchical framework is proposed in this paper to review the literature.
terms of price volatility (price variation through time at every step of the food chain) for different food products, there would appear to be a clear smoothening effect downstream in the food chain. This is essentially caused by the fact that raw material represents only a small share of the cost of the final food .

· Food chains differ from food webs in that they are showing a single line of feeding relationships. Food webs actually consist of many food chains together. A food chain is a linear display of energy movement and consumption. On the other hand, a food web shows interrelated relationships and multiple food chains in one.
