Why are producers not considered a trophic level?

Producers are indeed considered a trophic level. In fact, they form the first trophic level in any food chain or ecosystem. Producers are organisms capable of synthesizing their own food from inorganic substances, primarily through photosynthesis in plants or chemosynthesis in certain bacteria. They are the primary energy source for all other organisms in an ecosystem. Primary consumers, which feed directly on producers, form the second trophic level, followed by secondary and tertiary consumers. Decomposers, which break down organic matter, occupy the final trophic level. Therefore, producers play a crucial role as the foundation of energy transfer and sustenance within an ecosystem.
