Food chain definition class 10

Energy is not created or destroyed. The food chain starts with the producer or plants that convert solar energy into the usable form of energy food by the process of photosynthesis which is then eaten by consumers. A food chain is a linear network of links in a food web starting from producer organisms such as grass or trees which use radiation from the sun to make their food and ending at apex predator species like grizzly bears or killer whales detritivores like earthworms or woodlice or decomposer species such as fungi or bacteria a food chain also shows how the organisms are related with. In a community which has producers consumers and decomposers the energy flows in a specific pathway. A food chain represents unidirectional transfer of energy. When many such individual food chains occur in an ecosystem it is known as food web. A food chain is basically made up of pro ducers and consumers. Here the producers are consumed by the predators primary and secondary consumers and then the detritivores and finally by decomposers. The producers are represented primarily by the green plants and to a lesser extent by the photosynthetic bacteria. This occurs when one organism consumes another organism. A food chain describes how organisms get energy from eating other organisms. Food chain it is a sequence of ogranisms through which energy is transfered in the form of food by the process of one organism consuming the other. But it flows from one level to the other through different organisms. The consumers include all the other types of organisms in the ecosystem like herbivores carnivores etc. Or list of organisms living beings showing who eats whom is called a food chain.

What are food chains and explain their characteristics food chain is a sequence of organisms in a biotic community through which food passes with members of a step becoming food of the members of the next step of the sequence. In other words it is a list of who eats whom in a biotic community. A food chain explains which organism eats another organism in the environment. A food chain is a network of links in a food web. A food chain shows a direct transfer of energy between organisms. It begins with producer organism follows the chain and ends with decomposer organism. Food chains follow the flow of energy as it moves through the food chain. In scientific terms a food chain is a chronological pathway or an order that shows the flow of energy from one organism to the other. Components of food chain. All the food chains begin with a green plants. The starting point is the energy from the sun and this energy is traced as it moves through the food chain.
