The question asks about the number of biogeographic zones into which India is divided, according to the Wildlife Institute of India (WII). This is a factual question requiring knowledge of India's biogeographic classification.
C) 10 is the correct answer. The Wildlife Institute of India (WII) has indeed divided India into 10 biogeographic zones.
The question asks for the collective term for all plant and animal life in a specific region. We need to identify the option that encompasses both flora (plant life) and fauna (animal life).
Correct Option: A) Biota refers to the total collection of organisms (both plants and animals) of a geographic region or a time period. It is the most comprehensive term for all life forms in a given area.
The question asks for the specific term used to describe the plant life of a particular region or period. This is a direct definition-based question from the field of biology and ecology. We need to identify the correct biological term among the given options.
Correct Option: B) Flora is the term used to refer to the plant life of a particular region or period. For example, the "flora of the Himalayas" refers to all the plant species found in that mountain range.
The question asks to identify the type of biogeography that integrates geographical and ecological principles specifically for the protection of biodiversity. We need to evaluate each option based on its primary focus.
Correct Option: C) Conservation biogeography is the specific field that applies geographical and ecological principles directly to the protection of biodiversity. It uses spatial patterns of biodiversity and ecological processes to inform conservation strategies.
The question asks for the best description of an ecosystem. To answer this, we need to recall the definition and key characteristics of an ecosystem, which involves interactions between living organisms and their non-living environment.
Correct Option: B) A functional unit of nature where organisms interact among themselves and with the physical environment
This option accurately defines an ecosystem. It highlights two crucial aspects: first, it is a "functional unit of nature," implying self-sustainability and interconnectedness. Second, it explicitly mentions the interaction of organisms (biotic components) among themselves and with the "physical environment" (abiotic components). This comprehensive description aligns perfectly with the ecological definition of an ecosystem.
The question asks to identify an example of a man-made (artificial) ecosystem. An ecosystem is a community of living organisms (biotic components) interacting with their non-living environment (abiotic components). Man-made ecosystems are those created and maintained by humans, often for specific purposes, and require human intervention to sustain them.
C) An aquarium is a man-made ecosystem because it is created, designed, and maintained by humans to house aquatic life. Its existence and balance are dependent on human intervention.
