Primary consumers are the first to eat the producers (like small fish, insects, etc) Secondary consumers (foxes, larger fish, etc) consume the primary consumers, and tertiary consumers (sharks, humans, whales, etc.) consume the secondary consumers.

What would happen if the producers were removed from an ecosystem?

Elden [556K]

If producers were removed from an ecosystem, it would fall apart. Producers are the organisms at the bottom of the food chain, which produce glucose and nutrients for consumers. If producers were removed from an ecosystem, the consumers would have no nutrients and die, causing their predators to die, and so on.
