Answer 2

ANSWER::

Food chain, in ecology, the sequence of transfers of matter and energy in the form of food from organism to organism. Food chains intertwine locally into a food web because most organisms consume more than one type of animal or plant. ... In a predator chain, a plant-eating animal is eaten by a flesh-eating animal.

Grass → Grasshopper → Snake → Hawk → Fungi. All food chains begin with green plants or producers. Thus, the plants or producers constitute the first trophic level. Example: Grass.
