The grazing food chain is an easier kind of food chain as it starts from the main producers (green plants), who are the dominant producers in various ecosystems throughout the planet. a)Grazing Food Chain . The green plants or producers are grazed by herbivorous animals which are further eaten by carnivores. A food chain starts with producers and ends with top carnivores. Either may be the first member of a grazing or a detrital food chain. Producers utilize the radiant energy of sun which transforms to chemical form, ATP during photosynthesis. 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. B. Detritus food chain. Grazing Food Chain and Detritus food chain are the two important types of food chains in an ecosystem. Q41. Producers are any plant or other organisms that produce their own nutrients through photosynthesis. Herbivores, in turn, are eat… It starts from the dead organic matter and decomposers called detritivores as the first trophic level. D. Predator food chain. ... Producers have the lowest energy conversion efficiency. Types of food chain - definition. Trophic leaves in a food chain are formed by. Grazing Food Chain: The grazing food chain is a type of food chain that starts with green plants, passes through herbivores and then to carnivores. Producers, who make their own food using photosynthesis or chemosynthesis, make up the bottom of the trophic pyramid. The transfer of food energy from the producers, through a series of organisms (herbivores to carnivores to decomposers) with repeated eating and being eaten, is known as food chain. A peacock eats snakes which eat frog these eat hoppers which in turn thrive on leaves of the plants, the peacock is, Q14. Producers are autotrophs, or "self-feeding" organisms, that make their own organic molecules from carbon dioxide. Types of Food Chains: 1) Grazing food chain and 2) Detritus food chain; Grazing food chain In grazing food webs, energy goes from photoautotrophs to herbivores and then onward to carnivores. Converters or transducer organisms in the food chain are called (A) Herbivores (B) Carnivores (C) Decomposers (D) Producers. Grazing food chain starts with green plants which are the producers. Photo autotrophs like plants use light energy to build sugars out of carbon dioxide. In some food chains, food chains end up with detrivores such as mealybugs or even decomposing organisms such as bacteria. Both pathways are important in accounting for the energy budget of the ecosystem. Detrital food chain The components of detritus food chain, the detritivores include organisms like algae, bacteria, fungi, insects, and centipedes. Which one is not a factor of the abiotic environment? The consumers which start the food chain, utilising the plant or plant part as their food and ends with carnivores as consumers at the last level, with the herbivores being at the intermediate level, constitute the grazing food chain. The biosphere's food web is made up of grazing and detrital food webs. Feed the herbivorous; Feed the carnivorous; Clean the atmosphere; Capture solar energy; Answer:4.

Food chains are the basic unit of any ecosystem, connecting with one another to form the food webs that map the interactions of life on Earth. The various levels in the grazing food chain are linked to each other like links in a chain. Advertisement - Continue Reading Below The levels are often called trophic levels, and they suggest a particular order for the passage of energy through the food chain. Primary consumers in the detritus food chain are, Q7. 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 interactions of these two parts of a temperate deciduous food web are displayed in Figure 31.18. Grazing Food Chain: It starts with green plants (primary producers) and culminates in carnivores Example: Grazing food chain in Ocean ecosystem Phytoplankton Zooplankton Squid Sharks 20 2. 2. Furthermore, in a predator (grazing) food chain, a plant-eating animal is fed on by a flesh-eating animal. Completing the CAPTCHA proves you are a human and gives you temporary access to the web property. In a terrestrial ecosystem, major producers are herbaceous and woody plants. Parasitic food chain: This food chain starts from herbivore but food energy passes from larger to smaller organism without outright killing as in case of predator.
