After the offshore oil rigs are finished drilling, the platforms are sunk into the ocean. The impact this has on the organisms in the area is that "The platform provides a habitat for organisms."
This is evident in the fact that the platform surface or texture is soft, sandy, or muddy thereby making it easier for organisms like corals, sponges, fish, and many organisms, to create a new marine ecosystem.
The general theory is that mitochondria and chloroplasts began initially as separate cells that were "eaten" by larger cells, but not digested and simply passed on due to their advantages.<span />
Fermentation occurs in anaerobic respiration, and produces less energy than in aerobic respiration due to the lack of ETC because oxygen is not present.
Organisms that belong to the kingdom Protista are unicellular, and eukaryotic (cells with a true nucleus and membrane-bound organelles). Protists can be both heterotrophic and autotrophic, and they usually move by flagella or cilia.
