Hint: The food chain is divided into various stages in which the primary consumers have some special ability as they digest cellulose and their body have special four chambered stomach in which rumen is the largest part and this is the reason they are known as ruminants. Some insects and birds are also considered primary consumers.
Complete step-by-step answer:
Primary consumers are the organisms feeding on the autotrophs or producers, which are plants so the primary consumers will be Herbivores like a cow, sheep, goat etc.
Additional Information:
Food chain is a series in which one organism is dependent on another organism for their energy requirement.
There are certain types of organisms on earth in which plants are known as producers or autotrophs while consumers are considered heterotrophs which means they depend on food on others. Consumers can be classified into three categories Primary consumer, Secondary consumer, and Tertiary consumers.
Primary consumers are herbivore (like cow, sheep, goat, deer), secondary consumers are first-order carnivore(like lion hawk snakes) which means they feed on the herbivore, tertiary consumers (like humans) are a second-order carnivore, they feed on the secondary consumers they are the top predators and have no natural enemy.
Scavengers feed on the dead animal and plant bodies. Saprophytes are the organisms that feed on dead and decayed organic material present in the environment and play an important role in maintaining the balance of minerals and nutrients in the environment.
So, the correct answer is, ‘Herbivore.’
Note: In food chain energy is harvested by the autotrophs and is transferred from one trophic level to the other. The energy transformation is done by a 10 percent transfer rule which states that when an organism feeds on another organism only 10 percent of energy is transferred.
