Microbes

5. Primary producers (phytoplankton) and consumers (zooplankton) that drift with the currents
7. Green, brown, or red organelles with layers of internal membranes that contain photosynthetic pigments
9. Organisms that can use energy (usually solar) to make organic matter
10. A statement about the world that might be true
12. Protozoans that have many hair-like cilia, which are used in locomotion and feeding.
14. Undersea hot springs associated with mid-ocean ridges and other geologically active environments
15. Organisms that manufacture organic matter from CO2, usually by photosynthesis
17. A methane-producing archaeon
18. A sequence of nucleotides in the DNA molecule that directs the production of a particular protein
19. Organisms with cells that contain a nucleus and other organelles that are enclosed by membranes
20. Particles of dead organic matter

1. The complete genetic formation contained in the DNA of an organism
2. A complex carbohydrate characteristic of plants and other primary producers
3. Sediments made up of the skeletons and shells of marine organisms; siliceous ooze is made of silica, calcareous ooze of calcium carbonate
4. The molecule used to store and transfer energy in metabolic reactions
6. DNA and RNA, complex molecules that store and transmit genetic information
8. All the chemical reactions that take place in an organism
11. Organisms with cells that do not have a nucleus or most other organelles
13. Organisms that cannot make their own food and must use the organic matter produced by autotrophs
16. Made of calcium carbonate (CaCO3)
