They have no purpose whatsoever!

Fish are very important to the Earth uc they maintain a constant balance of our ecosystems ie they take in algae as oxygen much like we do via photsynthesis and continually give back via Co2 to replenish the algae. The fish does the same thing we do to survive - inhale oxygen and breathe out carbon dioxide.

The algae depends on our carbon dioxide to live much like the rainforests that

do but uc the balance of this is based on give and take, the tree via photosynthesis creates oxygen for us to live much like the algae of the seas. Yet it cannot survive without our breathing- our carbon dioxide and many more creatures that take in oxygen and let go of carbon dioxide - That make any sense ?
