Ecosystem Structure & Energy Flow — NEET Biology
📚 Practice ConceptWe will first look at the structure of the ecosystem, in order to appreciate the input (productivity), transfer of energy (food chain/web, nutrient cycling) and the output (degradation and energy loss). We will also look at the relationships – cycles, chains, webs – that are created as a result of these energy flows within the system and their inter- relationship.
Which of the following statements regarding the structure and function of an ecosystem are NOT correct? S1. The species composition of an ecosystem is solely determined by the types of plants, with animal species playing a secondary role. S2. Stratification is an example of a functional aspect of an ecosystem, illustrating the dynamics of energy transfer between trophic levels. S3. Biotic and abiotic components interact to create a characteristic physical structure for each ecosystem, but this interaction is not crucial for its overall function. S4. Productivity, decomposition, energy flow, and nutrient cycling are the four fundamental structural components of any ecosystem. S5. The top vertical strata in a forest are typically occupied by herbs and grasses due to their requirement for maximum sunlight.
