Solution
The correct option is A herbivores
Food chain is a chronological series of organisms each depending on other for food. It also explains the feeding pattern or relationship between living organisms.
Different organisms occupy different levels in the chain and each level is referred to as trophic levels.
Producers are present at the bottom or first trophic level of the food chain by synthesising their own food, followed by primary, secondary and tertiary consumers. Hence option d is incorrect.
The sun being the ultimate source of energy radiates sunlight which producers (Grass) are able to utilise and synthesise the food. Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.
Consumers are dependent on plants for food. It includes herbivores that eat plants, carnivores that eat herbivores and other animals.
Herbivores are known as primary consumers present at the second trophic level feeding on producers. Hence option a is correct.
Carnivores eat herbivores and come later in the food chain hence are known as secondary consumers. Hence option b is incorrect.
The herbivores (deer) are eaten up by secondary consumers (fox) or primary carnivores and present at third trophic level which is further eaten up by top carnivores (tiger) at fourth trophic level called secondary carnivores or tertiary consumers.

Decomposers are part of the detritus food chain (DFC), they depend on dead and decaying matters for their food. Examples include bacteria and fungi. Hence option c is incorrect.
