Question

In a food chain, the herbivores are represented by
A. Producers
B. Primary consumers
C. Secondary consumers
D. Decomposers

Answer 1

Food chain is a sequence of organisms those are interlinked in their feeding habit. The smallest is being fed upon by a larger one and which in turn feeds a still larger one etc. Food chains follow just one path of energy as animals find food.

Complete answer: The trophic level of an organism is the number of levels it is from the start of the chain. A food web also known as the food chain begins at a trophic level number 1 which is regarded as primary producers such as plants and level 2 is of herbivores whereas carnivores at level 3 or higher and finally finishing with apex predators at level 4 or 5.
Trophic levels can be represented by numbers, beginning at level 1 with plants.
Level 1: It includes plants and algae that make their own food and are known as producers.
Level 2: It includes herbivores that eat plants and are called primary consumers.
Level 3: This level includes carnivores that eat herbivores are called secondary consumers.
Level 4: Tertiary consumers come at this level which includes carnivores that eat other carnivores.
Apex predators are not eaten up by any of the other animals, so that’s why they are at the top of the food web. An example of food is: Grass is the first trophic level known as a producer which gets eaten up by the primary consumer such as goat and the further primary consumer gets eaten upon by the secondary consumer such as man.
So, the correct option is option B. Primary consumers

Note: A food web is all of the food chains in an ecosystem. Each and every organism occupies a particular trophic level or position in the food chain. Producers are always at the bottom of the food chain because they are the only organism that synthesized their own food.
