Understanding the Assertion and Reason
In this question, we are presented with two statements: an assertion (A) and a reason (R) related to trophic levels and food chains.
Assertion (A): Trophic levels are formed by only plants.
- This statement is false.
- Trophic levels include not only plants (producers) but also herbivores (primary consumers), carnivores (secondary and tertiary consumers), and decomposers. Thus, plants are just one part of the trophic level hierarchy.
Reason (R): Food chains and webs are formed due to linked organisms on the basis of their nutrition.
- This statement is true.
- Food chains and webs illustrate the flow of energy and nutrients through various organisms, linking them based on their roles in an ecosystem (producers, consumers, and decomposers).
Correct Answer Explanation
Given the evaluation of both statements:
- Assertion (A) is false as it incorrectly suggests that trophic levels are exclusive to plants.
- Reason (R) is true as it accurately describes how organisms are interconnected in food chains and webs.
Since the assertion is false and the reason is true, the correct choice is:
Option D: Assertion (A) is false but reason (R) is true.
This distinction clarifies that while the reason correctly explains the ecology of food chains, the assertion misrepresents the concept of trophic levels.

Directions: In the following questions, a statement of assertion (A) ...
A trophic level is the position of an organism in a food chain. A food chain starts with producers which are green plants and occupy the lowest trophic level. The highest trophic level is occupied by carnivores which feed on lower trophic levels for energy. A simple food chain is represented as
Plant ---> Herbivore ---> Carnivore
Hence, trophic levels are formed by different organisms linked in a food chain.
