Question

Grass → Goat → Man →
In above food chain, man is
A) Top consumer
B) Secondary consumer
C) Primary consumer
D) Producer

Answer 1

Hint: Food chain involves a nutritive interaction between the living organisms of an ecosystem. In the food chain there is unidirectional flow of energy. A trophic level is a crowd of bions within an ecosystem which hold the corresponding level in a food chain.

Complete answer:
Before we find the correct answer, let us understand a little more about trophic levels.
In science, the trophic level is the view that a bion remains in a food chain - what it consumes, and what consumes it. Trophic level is classified into four:
>Producer
>Primary consumer
>Secondary consumer
>Tertiary consumer

>Option A: Top consumers are seabirds– petrels- and killer fishes, which will use about any other tundra as food. Therefore, this is an incorrect option.
>Option B: The second trophic level contains herbivores, these bions gain strength by consuming primary generators and are termed, primary consumers. Trophic levels three, four and five hold omnivores and carnivores. Trophic level three holds omnivores (Example: Man) and carnivores which consume herbivores; these are the secondary consumers. Therefore, this is the correct option.
>Option C: The bions that eat the producers are the prime consumers. They manage to be modest in size and there are several of them. The primary consumers are herbivores. Grasshoppers, termites are examples of primary consumers. Therefore, this is an incorrect option.
>Option D: Algae and plants will make their own food and are termed as producers. Therefore, this is an incorrect option.

Thus, Option (B) Secondary consumer is the correct answer.

Note:The feeding sites in a food chain or web are termed as trophic levels. Many consumers serve at more than one trophic level. People/ Humans, for instance, are primary consumers when they consume plants such as vegetables. They are secondary consumers when they consume beef. They are tertiary consumers when they consume salmon.
