Write the kingdom that corresponds with the defining characteristic
12. Ecologically diverse; some cause diseases and some are beneficial to humans.
13. Found in the most extreme environments like volcanoes, brine pools, and the guts of cows. Cell
membranes contain unique lipids.
14. Most feed on dead or decaying organic matter. Also secrete digestive enzymes into their food
source.
15. Photosynthetic autotrophs, which means they can manufacture their own food by the energy from
the sun.
16. Some share characteristics with plants, such as being photosynthesizers while others share
characteristics with animals, such as being heterotrophic.
17. Large group of organisms of which all have the ability to move during at least part of their life
cycle.
Write the kingdom that corresponds to the examples (18-23).
18. Ameoba, paramecium, slime molds
19. Escherichia coli, cyanobacteria
20. Extreme halophiles, methanogens
