6. f.

Explanation:

• In a food chain, each organism is either a producer (makes its own food, usually plants) or a consumer (eats other organisms).
• For 1 (a): The plant (producer) is eaten by a primary consumer. Mice or small rodents are common primary consumers that can be preyed on by owls.
• For 2 (b): Worms (detritivores/consumers) need a producer as their food source. Plants (like grass or other small plants) are producers.
• For 3 (c): Rabbits (primary consumers) are prey. Foxes, wolves, or other medium - sized carnivores can be the next link.
• For 4 (d): Tigers (top carnivores) need a primary consumer. Deer or other large herbivores can fit this role.
• For 5 (e): Grasshoppers (primary consumers) are prey. Birds or small carnivorous insects (like praying mantises in some cases) can be the next link.
• For 6 (f): Mice (primary consumers) need a producer. Grains or plants (like the wheat - like plant in the first food chain) can be the producer.
