In large numbers, these organisms can cause “red tides” that are responsible for the killing of large numbers of fish and other invertebrates. A. Diatoms B. Euglenids C. Dinoflagellates D. Oomycetes E. Kinetoplastids 30. This phylum is characterized by a gametophyte dominant alternation of generations lifecycle A. Red algae B. Mosses C. Green algae D. Gymnosperms E. None of the above 31. The ostrich and emu look very similar and live in similar habitats, however they are not very closely related. This is an example of A. Divergent evolution B.
