Primary (or first-level) consumers: Identify 2-3 species.
Secondary (or second-level) consumers: Identify 2-3 species.
Tertiary (or third-level) consumers: Identify 2-3 species.
Quaternary (or fourth-level) consumers: Identify 1-2 species.
Write down the species you’ve identified for each consumer level in the ecosystem.
