To review:
The red tides are produced by the overproduction of dinoflagellates and can be caused by fertilizers that run off to coastal water. It is the main reason for the death of aquatic as well as wildlife organisms. Also, review the reason for the drastic cutbacks in the use of fertilizers, which will lessen the red tides.
Introduction:
Dinoflagellates are single-celled eukaryotic organisms, which show both autotrophic and heterotrophic modes of nutrition. There are some species that are photosynthetic symbionts, and some are bioluminescent. Dinoflagellates also show a symbiotic relationship with another marine organisms. Fertilizers are the synthetic material that help in the growth of the crop or plant.

- EVOLUTION LINK The number of protonephridia in a planarian is related to the salinity of its environment. Planaria inhabiting slightly salty water develop fewer protonephridia than those inhabiting less salty water, but the number of protonephridia quickly increases when the concentration of salt in the environment is lower. How is this increase adaptive?
