Some are swimming animals (fishes, sharks that move independently of water current) And others are tiny organisms Question 6: What would happen if the sea biodiversity were not maintained? => The marine of life would be at stake (if the sea biodiversity were not maintained)  ... overcome the challenges of the depth?
