Question

In an ecosystem, trophic level of man is
A. Producer
B. Herbivore
C. Omnivore
D. Carnivore

Answer 1

Hint: In an ecosystem, the trophic level is the position occupied by an organism in a food web. There are four trophic levels-producers, primary consumers, secondary consumers, and tertiary consumers.

Step by step answer:Ecosystem is a region which has all the species and abiotic factors residing together. Trophic levels exist in a food chain. A food chain is a sequence or order of species which demonstrates the food pattern of animals.
The food chain depicts four trophic levels are-
Producers: which produce food like plants
Primary consumers: which consume food obtained from plants directly like deer,
Secondary consumers: which consume primary consumers like snake and tertiary consumers which produce secondary consumers like eagle.
Consumers are of five types, herbivores, carnivores, omnivores, scavengers, and decomposers. Herbivores feed only plant and plant products for nutrition. Carnivores depend only on meat and flesh of other animals for nutrition. Omnivores feed both plants and animals for survival. Scavengers only feed on the dead. Decomposers feed on the remains of the dead and also the feces of the living. The examples are deer, lion, crows, vultures, and earthworms for each type of the consumer respectively.
As humans consume both animal meat and plant products, they are omnivorous.
So, the correct option is option C

Note: The energy is majorly lost in every step. Also, the contamination also increases as we move forward up the food chain. This means the primary consumers obtain the maximum energy and least contamination whereas the tertiary consumers obtain the least energy and maximum contaminated food.
