Answer 1

I think the odd one is Aquarium

Answer 2

Answer:

Aquarium

Explanation:

• An aquarium is a man-made system, and as a result, it lacks producers, food chains, and decomposers. Both recycling and self-cleaning are absent. However, a lake or pond is a self-sufficient, natural ecosystem with a flawless nutrient recycling system.

• We don't need to clean ponds and lakes because they are naturally occurring ecosystems with built-in natural decomposers and cleansers. Aquariums are man-made habitats that typically lack all the components of a natural ecosystem.

• You wouldn't be able to use an aquarium filter for a pond because it isn't powerful enough, but a pond filter should never be used in an aquarium because they aren't designed for that environment. Pond filters are typically rated to the water volume of the pond, and they must be capable of filtering the total volume at least once per hour, preferably twice.
