Correct option is B
The correct order follows the hierarchy of biological organization, starting with the most basic level (populations) and moving to the larger, more complex levels:
- Populations: Groups of individuals of the same species living in a particular area.
- Communities: Populations of different species interacting in the same area.
- Ecosystems: Communities of organisms interacting with their physical environment.
- Biomes: Large ecological areas on the Earth's surface, with distinct climates and ecosystems.
Information Booster:
- Populations refer to individuals of the same species living and interacting in a given area.
- Communities include all populations of different species that inhabit the same area.
- Ecosystems encompass both the biotic (living) and abiotic (non-living) components interacting together.
- Biomes are large geographic biotic units, typically characterized by distinct vegetation and climate patterns.
- Ecological studies often begin at the population level and progress to the biome level to understand biodiversity and environmental interactions.
- This order is important in understanding how ecological systems are organized and function in nature.
Additional Information:
- Option (a) "ecosystems < communities < biomes < populations" is incorrect because populations are the smallest and most basic organizational unit, not ecosystems.
- Option (c) "biomes < ecosystems < communities < populations" places biomes, which are large-scale environments, at the start of the order, which is not accurate.
- Option (d) "populations < ecosystems < communities < biomes" places ecosystems before communities, which contradicts the correct hierarchy as ecosystems are made up of communities and their environments.
