Conservation of biodiversity is important for:
Explanation
Option D is correct because the textbook context explicitly states that biodiversity conservation relates to 'millions of plant, animal and microbe species with whom we share this planet.' The text further emphasizes that 'All forms of life are so closely interlinked that disturbance in one gives rise to imbalance in the others.' Additionally, it mentions that 'Earth's rich biodiversity is vital for the very survival of mankind.' Since the context includes plants, animals, microbes, and humans, the most comprehensive and accurate answer is 'All organisms.' Options A, B, and C are incomplete as they exclude certain groups of organisms mentioned in the text.
Solution Steps
Step 1: Identify all organisms mentioned in the context - plants, animals, microbes, and humans.
Step 2: Note that the text states 'All forms of life are so closely interlinked' - indicating interdependence of ALL organisms.
Step 3: Conclude that since biodiversity affects all life forms, conservation is important for 'All organisms' (Option D).
