Description: Feed on zooplankton, forming an important link in the food web.

Trophic Level: Tertiary Consumer

Description: Prey on smaller fish, maintaining the balance in the ecosystem.

Trophic Level: Apex Predator

Description: The top predator in the ecosystem, preying on large fish and other marine animals.

Trophic Level: Secondary Consumer

2. The water temperature ranges from 50-77°F, it's salty, with moderate currents, depth varies, and it's mostly clear blue.

3. The ecosystem receives a good amount of sunlight each day, especially at the surface.

4. They live in the euphotic zone where sunlight penetrates.

5. The water source is saltwater.

6. The ecosystem is not directly connected to a freshwater source.

7. Seasonal changes include temperature variations and changes in food availability.

8. If primary consumers went extinct, secondary consumers would struggle to find food and populations would decrease.

9. Without decomposers, dead material would build up, and nutrients wouldn’t be recycled.
