This series or organisms taking part at various biotic levels form a food chain (Fig. 15.1). Each step or level of the food chain forms a trophic level. The autotrophs or the producers are at the first trophic level. They fix up the solar energy and make it available for heterotrophs or the consumers.

21 mar 2015 · A food chain describes how energy passes from one organism to another. Producers like plants get energy from the sun, consumers eat producers or other consumers, and decomposers break down waste. A food chain shows a single path of energy transfer, while a more complex food web links multiple food chains together as predators can have multiple ...
10 lip 2022 · This sequential interlinking of organisms involving the transfer of food energy from producers through a series of organisms with repeated eating and being eaten is called the food chain. A food chain may have 3-4 trophic levels.
22 sty 2024 · Food Chain: The sequence of living organisms in a community in which one organism consumes another organism to transfer food energy, is called a food chain. A food chain is unidirection where transfer of energy takes place in only one direction.
