Question

what is y-shaped food chain ? Explain with simple diagram.

Answer 1

Answer:

Y-shaped model of flow of energy in ecosystems. A the flow of energy in a single food chain; either grazing or detritus, is termed the single chain model. ... The lower food chain of plant—>termite—>aardvark is a part of the detritus food chain.

Answer 2

Answer:

H.T. Odum (1956) first presented the y-shaped model, although his brother E.P. The Universal model of flow of energy was presented by Odum (1983) and broadened this relationship.

What is Y-Shaped Food chain?

• The grazing food chain and the debris food chain frequently coexist in nature.
• For instance, if a herbivore dies naturally, a predator cannot eat it! As opposed to that, it joins the debris food chain.
• The grazing food chain and the detritus food chain are connected, according to the Y-shaped paradigm.
• The herbivore can be consumed by the predator of the decomposer.
• The top predator may then consume that predator. Another connection point is the fact that when a herbivore or top predator dies, their bodies are broken down by decomposers.
• In some ecosystems, the top predators also eat the decomposers, which they then employ as fertiliser for the plants.
• For instance, the large fish that live in ponds devour the mosquito larvae that are there.
• The model is known as the "Y-shaped model" because it resembles the letter "Y" from the side.
• One arm of the Y-shaped energy flow model describes the herbivore food chain, and the other arm describes the decomposer or detritus food chain.
• This is seen to be more realistic because it divides the two chains and follows the basic stratified structure of ecosystems.
