Primary Consumers
Definition
Primary consumers, also known as herbivores, are organisms that feed directly on producers (plants or algae) in an ecosystem. They obtain their energy by consuming plant material.
Analogy
Think of primary consumers as the vegetarians of the animal kingdom. Just like humans who eat plants for energy, primary consumers rely on plants to fuel their own growth and survival.
