Primary source of energy is dead organic matter called ‘detritus’ which are fallen leaves, plant parts or dead animal bodies. The food chain in which microorganisms break down the energy rich compounds synthesized by producers, Q39. Other articles where Grazing food chain is discussed: ecosystem: …living plants is called a grazing pathway; that in which the primary consumer feeds on dead plant matter is known as a detritus pathway. Furthermore, in a predator (grazing) food chain, a plant-eating animal is fed on by a flesh-eating animal. Each organism sits at a particular trophic level; for instance, the primary producers such as grass sit at trophic level 1 and the apex predators sit at trophic level 4 or 5. 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). The secondary consumers of this food chain include insect larvae, nematodes, etc. 2. In grazing food webs, energy goes from photoautotrophs to herbivores and then onward to carnivores. Thus plants are referred to as the primary source of food or producers in a food chain. In pyramid of food, the producers occupy, Q31.

Carnivores have better energy conversion efficiency than herbivores. Herbivorous; Carnivorous; Decomposers; Producers; Answer:4. • Producers in any grazing food chain. Converters or transducers organisms in the food chain are called. The flesh-eating animals, in this case, are non-producers, since they do not contain chlorophyll, a pigment required for the primary synthesis of food. The producers are represented primarily by the green plants, and, to a lesser extent, by the photosynthetic bacteria. For example, green plants, fruits, phytoplanktons, small plants, and algae are some examples of producers in a food chain. Primary producers (Autotrophs)-> Advertisement - Continue Reading Below In what way are decomposers like producers? A food chain starts with producers and ends with top carnivores.
