Question

how will you create an artificial aquatic ecosystem ,which is self sustainable​

Answer 1

a self sustainable artificial ecosystem (for eg. an aquarium ) can be created using the steps given below :

1. a large jar or tank is selected and filled with clean water
2. it is connected to an unrestricted oxygen supply (i.e. an oxygen pump or cylinder)
3. aquatic plants( like water ferns,hydrilla etc.) and animals(eg. fishes are added along with sand pebbles .etc. to atimulate aquatic life.
4. in an aquarium the aquatic plants act as producers and produce o2 , use co 2 released by consumers during the process of photosynthesis . decomposers clean up the the dead remains of organisms and act as natural cleaners of this ecosystem

Answer 2

Answer:

• Large jar filled with water, oxygen, food and aquatic plants and animals
• Oxygen pump
• Fish food

• Aquatic plants producers provides O₂ during photosynthesis
• Aquatic animals consumers release CO₂ for the process of photosynthesis
• Decomposers are also important for natural cleaning of the aquarium
