Consumer-Producer-Decomposer worksheet - Free Printable

To solve the problem of identifying whether each organism is a producer, consumer, or decomposer, we need to understand the roles these organisms play in an ecosystem:

1. Producers: These are organisms that can produce their own food through photosynthesis. They are typically green plants and algae.
2. Consumers: These are organisms that eat other organisms for energy. They include herbivores (plant-eaters), carnivores (meat-eaters), and omnivores (both plant- and meat-eaters).
3. Decomposers: These are organisms that break down dead organic matter and recycle nutrients back into the ecosystem. Examples include fungi, bacteria, and some insects.

Now, let's classify each organism based on its role:

---
