उत्तर
(a)
- Omnivore: Organism B
- Herbivore: Organism D
- Carnivore: Organism A
(b) Organism C is an autotroph. It synthesizes its own organic food from simple inorganic substances using solar energy via photosynthesis.
(c) The organisms A, B and D are heterotrophs as they obtain food from other organisms and cannot synthesise their own food.
(d) Organism C is a producer. Because it creates its own food using sunlight, it forms the foundational source of energy (organic matter) for an ecosystem.
(e) The organisms A, B, and D are consumers. They must consume other living organisms (plants or animals) to obtain energy.
(f)
- Organism A (Carnivore): Lion, Tiger, or Lizard.
- Organism B (Omnivore): Human, Bear, or Crow.
- Organism C (Producer/Autotroph): Green grass, Neem tree, or Algae.
- Organism D (Herbivore): Cow, Deer, or Rabbit.
