Which group of three living organisms forms a link in the food chain from Green plants to Hawk:
Show answer Hide answer
Answer: A. Grasshopper, frog, snake
Explanation
A classic food chain link leading to a hawk includes a primary consumer grasshopper, eaten by a frog, which is then preyed upon by a snake. Energy flows sequentially from the primary herbivore up through secondary and tertiary carnivores to the apex bird of prey. Each organism in this specific predatory sequence occupies an ascending trophic level culminating in the hawk. Food chains map the directional transfer of food energy from green plants through a series of specific organisms. Grasshoppers feed on grass as primary consumers, frogs act as secondary insectivores, and snakes serve as tertiary carnivores. Hawks occupy apex predator positions, preying upon snakes and other small vertebrates in terrestrial ecosystems.
Option B includes rats instead of frogs, creating a different dietary link that bypasses the aquatic amphibian stage. Option C lists millipedes and centipedes, which do not fit the standard linear grassland food chain leading to hawks. Option D combines earthworms and hens, representing a farmyard domestic chain rather than a wild ecosystem link.
