In an ecosystem, organisms can be classified into producers, consumers, and decomposers based on their roles. Here's how each of the listed organisms fits into these categories:
Producer:
- Grass: As a plant, grass is a primary producer that converts sunlight into energy through photosynthesis.
Consumer:
- Bear: Bears are typically omnivores, meaning they can consume a variety of foods, including plants (producers) and other animals (consumers).
- Rabbit: Rabbits are herbivores that primarily eat plants, making them primary consumers that rely on producers for their energy.
Decomposer:
- Worm: Worms, particularly earthworms, play the role of decomposers by breaking down organic matter and recycling nutrients back into the soil.
In summary:
- Producer: Grass
- Consumer: Bear, Rabbit
- Decomposer: Worm
