EcoSphere

This photo was taken January 30, 2017 on my roommates' dresser! Pictured is a little glass EcoSphere which is a completely enclosed ecosystem that can thrive from two to seven years. However, it is a totally self-contained and self-sustaining environment for the micro-organisms, small shrimp (Caridea), algae (Phaeophyceae), and bacteria that are existing in the filtered sea water. It is self-sustaining due to the ability for each of these organisms to utilize the resources provided within their habitat. The only necessary “care” that the EcoSphere needs is a light source which could be either indirect natural or artificial light. The algae uses this light source for photosynthesis as well as inorganic nutrients for energy then is able to releases oxygen to the habitat. Algae is then used as a food source for the non-photosynthetic organisms: small shrimp and bacteria. The bacteria also eats the wastewater from the shrimp to get their nourishment to survive and keep the seawater clean. Although this is not my favorite way to see these organisms, it is a great way to view and understand how the different organisms of an ecosystem relate and depend on each other up close and personal. The little to no care necessary in order to have these cute organisms as a “pet” is tempting, however, I think I will stick with plants and dogs!!
