Given below are two statements.

Statement I  : Vertical distribution of different species occupying different levels is called stratification.

Statement II : Identification and enumeration of plant and animal species of an ecosystem gives its species composition.

In light of the above statements, choose the correct answer from the options given below.

Statement I is correct. The vertical distribution of different species occupying different levels within an ecosystem is called stratification. This stratification often occurs in ecosystems such as forests or aquatic environments, where different species occupy distinct layers or zones based on factors like light availability, temperature, and nutrient availability.

Statement II is also correct. The identification and enumeration of plant and animal species within an ecosystem provide its species composition. This composition is crucial for understanding the biodiversity and ecological dynamics of the ecosystem. It helps scientists and conservationists assess the health of the ecosystem, track changes over time, and develop conservation strategies to protect its biodiversity.
