A food chain is a series of steps by which energy is obtained, used, and transformed by living things. For example; sunlight helps plants to grow, the plants are eaten by cattle, and lions eat the cattle. All living organisms of the biosphere are related to each other by a ..

"Food chain is a series of groups of organisms called trophic levels, in which, there is repeated eating and eaten by so as to transfer food energ..

While studying the biotic components in an ecosystem we have realised that food prepared by green plants is consumed by a series of consumers, both herbivores and carnivores, and finally broken down into their elements and released back into nature by decomposers in nature. The nutritiona..

Types of Food Chains - There are mainly two types of food chains operating in nature. a) Grazing food chain b) Detritus food chain. Grazing food chain is generally seen in ecosystems such as grasslan..

Characteristics of a Food Chain - In a food chain, a) there is repeated eating in which each group eats the smaller one and is eaten by the larger one. Thus, it involves a nutritive interaction between the biotic components of an ecosystem. b) the plants and ..

The different steps or levels in a food chain form different trophic levels. The illustration below is self-explanatory. This is the ecosystem that can exist on land. Trophic levels Thus a food chain of four levels is built up where green plants fix up the so..

Characteristics of Grazing Food Chain - a) These are directly dependent upon solar radiations as the primary source of energy and the producers (green plants) synthesize their plant biomass by the process of photosynthesis. Producers form the first trophic level. b) Herbivores o..
