Each food chain is a possible route that energy and nutrients can follow through the ecosystem. For example, grass produces its own food from sunlight. The food chain tells us how energy is transferred from one organism to another. It is a linear sequence of organisms (that is, energy flows in one direction).
The food web shows how many food chains are connected to each other. It's a more realistic interpretation of how food is consumed in an ecosystem. Now, let's study the trophic level. CA Maninder Singh has been a public accountant for the past 12 years and a professor for the last 16 years.

The term food chain refers to the sequence of events in an ecosystem, where one organism eats another and is then eaten by another organism. Decomposers also play a crucial role in this case, since aquatic decomposers distribute nutrients not only in the soil, but throughout the water column, feeding the plankton that form the basis of all aquatic food chains.
B) Interconnected food chains operating in an ecosystem that establish a network of relationships between several species are called a food network. There, microbes that never saw the sun extracted nutrients from compounds emitted into water from deep in the Earth's crust and produced chemicals that created entirely new food webs that had never been dreamed of on the surface. Food chains are the basic unit of any ecosystem and are connected together to form food networks that map the interactions of life on Earth. It starts with the primary source, such as the sun or hydrothermal vents, where producers produce food, continues with consumers or animals that feed on food, and ends with the main predator.
Ultimately, everything gets its energy from the Sun, and most food chains follow the pattern of herbivores, carnivores, perhaps one or two carnivores, supreme predators. By eating and excreting, decomposers return nutrients from dead organisms to the soil, nourishing plants that start the chains again. A) The sequence of living organisms in a community in which an organism consumes other organisms to transfer food energy is called the food chain. Organisms ranging from bacteria and worms to the noble cockroach feed on the dead and, in doing so, break them down into the nutrients that keep the food chain running.
Much of the ocean remains unexplored, and food chains in water-based environments are often complex and surprising to Earth's inhabitants.
