Food Chains PowerPoint Presentation free download Biology Diagrams How Do Food Chains Work? A food chain starts with sunlight, which is absorbed by plants and used to create food through photosynthesis. Herbivores feed on plants, gaining the energy stored in them. Carnivores then eat these herbivores, gaining the energy that the plants first absorbed from the sun. Higher-level predators or scavengers may
The figure 8.12 explains the flow of energy through a typical food chain. Two types of food chains are present in ecosystems. They are the grazing food chain and the detritus food chain. Grazing food chain. Grazing animals play an important role in the transfer of energy to the carnivores in this type of food chain, hence the name grazing food

A food chain operates on energy transfer across trophic levels, where each level represents a stage in the chain. Producers at the base capture solar energy and convert it into chemical energy, which moves up the chain as each consumer feeds on the one below it. Decomposers break down dead organisms, returning
Because energy, in the form of heat, is lost at each step, or trophic level, chains do not normally encompass more than four or five trophic levels. People can increase the total food supply by cutting out one step in the food chain: instead of consuming animals that eat cereal grains, the people themselves consume the grains. Because the food chain is made shorter, the total amount of energy
Understanding Food Chains: A Simple Guide for Kids Biology Diagrams
Learn how a food chain works, how it differs from a food web, and how it's affected by biodiversity loss. A food chain is a linear pathway that shows how energy, in the form of food, travels through an ecosystem. Food chains only have four or five links so if one link is missing, due to pollution or over harvesting, the results could be devastating for the remaining plants and animal Autotrophs: The Producers. As mentioned earlier, a food chain starts with the primary producers at the base who can make their own food. These organisms are called autotrophs.Autotrophs can make their own food using their own organic compounds from simple molecules like carbon dioxide in the presence of sunlight. Autotrophs come in two types:. 1.
