1. Biologists can set up an ecosystem in a small, sealed aquarium that continues to function without maintenance for years. Describe the minimum biotic and abiotic components it must contain to remain balanced and stable.
To determine:
The minimum abiotic and biotic components required to maintain a balanced and stable sealed aquarium for years.
Introduction:
To maintain a balanced and stable sealed aquarium, it has to act like an aquatic ecosystem. It should contain the adequate and required abiotic and biotic components. A sealed aquarium ay be thought of as a mini lake and hence a similar kind of ecosystem needs to be created.
Explanation of Solution
The concept of creating is a sealed aquarium is similar to making a nature aquarium. The major requirements are primary producers, consisting of phytoplankton, algae and diatoms. Consumers such as zooplanktons, small and large fishes are required and decomposer microbes are must. There should be appropriate amount of sunlight or artificial light that can help in photosynthesis along with supply of oxygen and carbon dioxide. An artificial bedrock also needs to be created.
Hence, it may be concluded that, an artificial sealed aquarium needs appropriate abiotic and biotic components.
