Bacteria break down the shrimps' wastes. The breakdown products provide nutrients to the algae and bacteria upon which the shrimp feed. The manufacturer states that shrimp live in the EcoSphere for an average of 2 to 3 years, and are known to live over 10 years. A magnetic scrubber is enclosed in each EcoSphere. By passing another magnet over the outside of the glass, the owner can manipulate the scrubber to clean the inside of the EcoSphere.
Thus plants using C 4 photosynthesis may be able to survive for at least 0.8 billion years and possibly as long as 1.2 billion years from now, after which rising temperatures will make the biosphere unsustainable. Currently, C 4 plants represent about 5% of Earth's plant biomass and 1% of its known plant species.
