A balanced aquarium is an example of a very small ecosystem. It is self-supporting because the requirements for a stable ecosystem are present: ENERGY (1) is supplied to the ecosystem by light. There are PLANTS (2) to change the light energy into the organic molecule of energy (glucose).RECYCLING (3) of materials occurs during photosynthesis and respiration. During photosynthesis, plants use light energy and carbon dioxide to form glucose. balanced aquarium is an example of a very small ecosystem.
