The termite gut environment is lacking a fresh supply of oxygen O2. However, it is rich with food due to the presence of bacteria that contain enzymes capable of breaking down cellulose and lignin, the macromolecules that make wood. Use this information to determine which of following protista groups is more likely to be found in a termite gut. a. Diatoms
b. Radiolaria
c. Parabasilids
d. Rhodophyta
e. Foraminifera (Forams)

c. Parabasilids

Explanation:

Termites are unable to digest cellulose and lignin by themselves. They need microorganisms living in their guts to provide the necessary enzymes to break down these molecules. This relationship turns to be mutualistic, in which both organisms are beneficiated. The microorganism is an endosymbiont.

Parabasilids are unicellular flagellated protists, most of them symbionts with animals. Flagella are characteristics of this group, arranging into one or more groups in the anterior region of the cell. Many species are commonly found in the digestive tube of termites. Parabasilids help their hosts to digest cellulose through enzymatic action. They are anaerobic organisms and lack mitochondria, making them capable of living in an environment with no fresh supply of oxygen O₂. Termites gut provide all the necessary conditions for endosymbiont´s growth, reproduction, and development.

from my research i have to the conclusion that decomposers, such as fungi, bacteria and invertebrates, play a critical role in nutrient cycling and without them the earth's ecosystem may not support life as we know it. elements such as carbon, nitrogen and phosphorus exist in limited amounts on earth, although huge amounts of carbon are being released into the atmosphere from underground sources now by humans. it is still extremely important that other nutrients be retained by the process of re-use. decomposers are organisms that are able to chemically break down dead material and make these elements available for use by other organisms. without this breakdown of dead material, dead bodies would pile up. so decomposers also play a role in clean up also. without them, life might not continue as we know it and dead material would overwhelm the earth.    

the match lol
