Question

Primary consumers are
A.Primary carnivorous
B.Secondary carnivorous
C.Herbivorous
D.Tertiary carnivorous

Answer 1

Primary consumers are the ones which feed on the producers those are autotrophic plants. Primary producers like plants prepare their food through the process of photosynthesis and many feeding animals feed on these plants to gain energy and these primary consumers can be algae, fungi etc., primary consumers are dependent consumers because they depend on primary producers.

Complete answer:
A.Primary carnivorous: Primary carnivorous are cat Buffalo, horses, and most birds because they depend on herbivorous which are plant-eating animals they eat animals which depend on primary producers hence they are not considered as primary consumers because they do not tend to eat primary producers such as plants directly but they depend on animals which eat plants
So option A is not correct
B. Secondary carnivorous: These carnivores include snakes, spiders and bears; they do not eat plants but they eat meat organisms such as mice etc they depend on primary consumers but not on the primary producers directly.
So option B is not correct
C. Herbivorous: These include monkeys, koalas, cattle etc. these herbivorous they depend on primary producers their body is automatically and developed to depend on primary producers such as plants Hence herbivorous are considered as primary consumers as they depend directly on primary producers.
So option c is correct.
D. Tertiary carnivorous: Carnivorous are considered as top-level in food chain carnivorous animals as they include Whales, Eagles, cheetah, Tiger etc., these animals they depend on primary carnivorous or primary consumers and secondary carnivorous or secondary consumers they do not directly depend on primary producers hence they cannot be considered as primary consumers.
So option D is not correct.

Hence Option C is the answer to this question.

Note:
Primary consumers and secondary consumers, primary carnivorous and secondary carnivorous and herbivorous animals are linked to each other through the ecological food chain because it is a chain in which one Organism depends on another Organism which can indirectly depend on another source for the survival and the living.
