The term ecosystem describes both the living and non-living components of an area that interact with one another. All the components are inter-dependant in some way with each other. An ecosystem may be aquatic or terrestrial.<\/p>\n
Advantages It is difficult to find a perfectly balanced ecosystem but you can make a model at home and observe how the ecosystem functions. <\/p>\n
This way you will not disturb the bed or any other plants or fish when you pour water. When the water is at least 1 inch higher than the bed, put the plants into the soil. As the water level goes up the leaves of the plants will also rise up. <\/p>\n
After the tank is full with about 4 inches left on top, stop pouring the water. Let the water settle for some time. Now introduce the fish one by one and close the top. <\/p>\n
Observation Observe whether some fish are destroying the plants or whether some fish are eating other fish. If the population of one species goes down dramatically, try and find the reason why this has happened. See what will bring back the balance- is it more fish of the same species, places for them to hide and be protected from predator fish, or more oxygen in the water? <\/p>\n
For your project display, describe the abiotic (nonliving) factors present. Explain why the living and nonliving elements are needed in the aquarium. Give reasons for selecting the organisms or type of fish and the plants. Explain what relationship the fish have with each other and the plants- are they prey-predator? Show where they are in the food chain. Note their life cycle. Describe their adaptations and interactions with each other and the environment. <\/p>\n
