As we add more CO2 to the atmosphere, it will eventually come back down as: meatballs carbonic acid, and acid rain condensation rain

You find an unknown species in a fishing net and are not sure where it came from. To keep it in the lab to learn more about it, and find out where it came from, what would be the best approach? Set up an estuary tank because the intermediate salinity is most likely to support life. Carefully monitor temperature, salinity, and oxygen levels to detect quickly if they are not correct. Use freshwater and lab temperatures because a freshwater environment is less stressful than a marine environment. Set up a standard marine tank because salinity and oxygen levels are similar in all marine environments. Set up an environment with low oxygen levels and low light levels to lower stress.

The number of trophic levels in an ecosystyem are limited.Comment.
