Question

comparison between consumer food chain/ predator food chain /parasite food chain and Detritus food chain

Answer 1

Food chain is a model that shows flow of energy and nutrients from one organism to another organism in an ecosystem. The length of a food chain depends upon the number of organisms. It starts from producer species such as tress or grass and ending at apex predator species such as grizzly bears or killer whales; detrivores such as earthworms or woodlice; or decomposer species like fungi or bacteria. A food also shows the relation between organisms as who they are related with each other by the food they eat. Plants and animals requires some type of food for survival. Plant produce their own found via photosynthesis process. Since they produce their own food they are called and producers while those organisms which do not produce their own food like animals and humans are known as consumers.

Answer 2

Explanation:   detritus food chain, energy comes from organic matter (or detritus) generated in trophic levels of the grazing food chain. It begins with detritus such as dead bodies of animals or fallen leaves, which are then eaten by decomposers or detritivores. These detritivores are in turn consumed by their predators. It is usually smaller as compared to the grazing food chain. Primary consumers are 'detritivores' including protozoans, bacteria, fungi, etc which feed upon the detritus saprophytically.

So the correct option is 'dead organic matter'.
