There are never more than four steps, because a lot of energy is lost at each step, and after three steps most of the available energy has been expended. Sometimes you'll see food chains with the sun at the beginning. Short food supply chain (SFSCs) is a broad range of food production-distribution-consumption configurations, such as farmers' markets, farm shops, collective farmers' shops, community-supported agriculture, solidarity purchase groups.More in general, a food supply chain can be defined as "short" when it is characterized by short distance or few intermediaries between producers and consumers. Password must contain at least one uppercase letter, a number and a special character. Primary consumers eat the producers. Only a single species of herbivores feeds on each plant species. The feeding positions in a food chain or web are called trophic levels. Food chains are short for several reasons: 1. every level of biological pyramid transfers about 10% of the lifetime consumption of energy to the next level, because organisms have to live. As apex predators atop the food chain, red wolves have done so much for its ecosystem by keeping various species populations in check. To understand why this limit on the number of consumers exists we need to study what happens to the energy as it flows along the food chain.
