There are many different kinds of marshes, ranging from the prairie potholes to the Everglades, coastal to inland, freshwater to saltwater. All types receive most of their water from surface water, and many marshes are also fed by groundwater.
Shrimp are marine crustaceans that are found on the bottom of the water in nearly every environment around the world. Shrimps are generally tiny in size, with some species of shrimp being so small that many animals cannot see them.hrimp mainly feed on algae and other plant particles along with tiny fish and plankton in the water. One species of shrimp is known to stun it's prey before eating it by making a loud noise with one of it's claws, that makes a snapping sound through the water.
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.
