Here's why:
* Primary Consumers: These organisms feed directly on producers (plants). They are herbivores.
* Fallfish Diet: Fallfish are omnivores, meaning they eat both plants and animals. However, their diet primarily consists of algae, aquatic insects, and other invertebrates, making them primarily herbivorous.
Therefore, Fallfish are considered primary consumers as they obtain their energy from consuming plants and small animals. They play a crucial role in the ecosystem by transferring energy from producers to higher levels of the food chain.
