Mycorrhizae increase the plants’ uptake of water and essential nutrients, particularly phosphorous, which doesn’t spread readily in soil. In exchange, the plants provide the fungi energy in the form of carbohydrates. This partnership enables both plants and fungi to survive in nutrient-poor places where they otherwise might die. Major development projects are taking place in oceans across the globe all the time, enterprises that will provide shelter and food for a vast number of fish, mussels, urchins, and other marine life. Cyanobacteria also use carbon dioxide to synthesize all of their biological molecules and thus remove it from the atmosphere. Since carbon dioxide is a major greenhouse gas, its removal by cyanobacteria affects the global carbon dioxide balance and may be an important mitigating factor in global warming.

A primer is like a mirror image of a short bit of RNA or single strand of DNA; that is, its sequence of nucleotides is the direct complement to the sequence of nucleotides in a known part of the target RNA or DNA. In this instance, the primer would be the mirror image of the beginning or end of the 16S rRNA sequence. Because complementary nucleotides pair up like the two halves of Velcro, the primer enables the scientist to pick out the 16S rRNA in the sample. The scientist then uses PCR to make millions of copies of these genes. She then has enough 16S rRNA to compare the sequences of the genes from her sample to libraries of stored 16S rRNA genes from numerous known bacteria. Heliozoa, radiozoa, and forams tend to be passive grazers and predators, relying on suitable food swimming or drifting past to come into contact with their pseudopods. Several species in the sarcodina group, including some species of amoebas, cover themselves with protective shell-like coverings called tests. These tests are stippled with many small and large openings through which water can flow in and out and through which the pseudopods protrude.
