Geology's Unifying Theory. Plate tectonics is the framework in which geologists study and understand the inner workings of the earth. It provides us with a way to tie together what once was considered unrelated geologic processes and events.
Protists live in almost any environment that contains liquid water. Many protists, such as algae, are photosynthetic and are vital primary producers in ecosystems, particularly in the ocean as part of the plankton.ome protists are significant parasites of animals (e.g., five species of the parasitic genus Plasmodium cause malaria in humans and many others cause similar diseases in other vertebrates), plants (the oomycete Phytophthora infestans causes late blight in potatoes) or even of other protists.
Extremophiles are microbes that live in conditions that would kill other creatures. It was not until the 1970's that such creatures were recognized, but the more researchers look, the more they discover that most archaea, some bacteria and a few protists can survive in the harshest and strangest of environments.any of these hot springs are contaminated with sulfur, however, and the water pH can be below five-acidic. Also acidity, unlike heat, does not fall off outside the area of geological activity. Other places where acidophiles occur include polluted places, where industry or mining has left acidic waste.
