NEET Botany Ecosystem Components MCQ Question
Which of the following statements about ecosystem components is correct?
Abiotic components include air, water, and soil, while biotic components consist of producers, consumers, and decomposers.
Stratification refers to the random distribution of species in an ecosystem without any hierarchical structure.
Primary productivity is solely determined by the number of consumers present in an ecosystem.
Species composition can be defined as the vertical distribution of different species occupying various levels in an ecosystem.
Correct Answer
Detailed Explanation
Statement A accurately describes the distinction between abiotic and biotic components of an ecosystem as stated in the NCERT context. Statement B is incorrect because stratification reflects a structured arrangement of species, not random distribution. Statement C is erroneous as primary productivity is primarily associated with producers, not consumers. Statement D mixes definitions, as stratification specifically relates to vertical distribution, while species composition refers to the identification of species.
