Final answer:
All listed items, including biotic factors like coral and clownfish and abiotic factors like rocks and the water filtration system, should be included on the list of factors in the aquarium ecosystem as they play a vital role in its function and maintenance.
Step-by-step explanation:
When Ms. Brown's class is making a list of all the factors in an aquarium ecosystem, they should include both biotic and abiotic factors. Biotic factors are the living components, which in this instance include coral, seaweed, clownfish, and sea turtle.
Abiotic factors are non-living elements that affect the ecosystem, such as rocks and the water filtration system. Together, these form the complete set of factors contributing to the ecosystem in the aquarium.
Abiotic factors like light, temperature, and salt content play a significant role in shaping marine biomes, impacting the types of organisms that can thrive in these environments. The aquarium's filtration system helps maintain the balance of these conditions, making it an essential part of the ecosystem.
Similarly, the rocks provide a physical structure and surface for organisms such as seaweed and coral to attach, making them another abiotic factor within the ecosystem.
