Given below is a list of autotrophs and heterotrophs. With your knowledge about food chain,establish various linkages between the organisms on the principle of 'eating and being eaten'. What is this inter-linkage established known as?
Algae,hydrilla,grasshopper,rat,squirrel,crow,maize plant,deer,rabbit,lizard,wolf,snake,peacock,phytoplankton,crustaceans,whale,tiger,lion,sparrow,duck,crane,cockroach,spider,toad,fish,leopard,elephant,goat,nymphae,spirogyra.

(N/A) The natural interconnection of food chains containing producers,consumers,and decomposers in a complex,cross-linked network is called a food web.
$(i)$ Apex predators/High-level carnivores: Tiger,Lion,Leopard (Highest trophic level).
(ii) Secondary/Tertiary consumers: Spider,cockroach,lizard,wolf,snake,toad,fish,crane,peacock,crow,sparrow,duck,whale (Third/Fourth trophic level).
(iii) Primary consumers: Crustaceans,grasshopper,deer,rat,squirrel,rabbit,elephant,goat (Second trophic level).
(iv) Producers: Phytoplankton,algae,hydrilla,maize plant,nymphaea,spirogyra (First trophic level).
