Chapter 20.7, Problem 1CR
Summary Introduction
The deep sea surface is said to be benthic with the depth range of 500 to 4000 meters and above. The world’s deepest part of the sea ever known is Mariana trench with maximum depth of 10,000 meters. These benthic environment is completely void of sunlight penetration.

Which of the following prokaryotes has a relatively large surface-to-volume ratio for rapid gas exchange, despite having one of the largest cytoplasmic volumes of any known eubacterial cell?
the archaeobacterium Halobacterium halobium
the archaeobacterium Nanoarchaeum equitans
the eubacterium Rhodopseudomonas viridis
the eubacterium Epulopiscium fishelsoni
the eubacterium Escherichia coli
Explain two ways in which archaea metabolize inorganiccompounds in extreme environments.
The unicellular cyanobacterium Prochlorococcus sp. is the most abundant photosynthetic microbe in tropical and subtropical oceans. At least two ecotypes exist: one is adapted to high light and the other to lower light intensities. How does the presence of these two ecotypes contribute to their physiological success and their numerical success? How would you determine the amount of fixed carbon they contribute to these open-ocean ecosystems?

- Ruminants (like cattle) are herbivores but lack the necessary enzymes to digest cellulose from plants. Part of the digestive tract of ruminants contains a microbial community that can break down cellulose. These microbes gain energy from the plant material, and byproducts of their metabolism provide the host with a source of Carbon and energy. What type of symbiosis does this relationship describe?arrow_forwardMethanopyrus kandleri and Pyrolobus fumarij are bacteria that live near hydrothermal vents under the oceans. Temperatures at these vents can reach well over 100 degrees Celsius. Both organisms obtain energy from hydrogen but Methanopyrus kandleri grows best at 98 degrees Celsius while Pyrolobus fumarij prefers to reproduce at temperatures above 100 degrees Celsius. These bacteria provide the base of a food web at the bottom of the ocean floor. What questions could a student ask in order to investigate this difference between the bacteria? A. What kind of heat tolerance do other nearby organisms have? B. Does the Methanopyrus kandleri live farther away from the vent than the Pyrolobus fumarij? C. Does Methanopyrus kandleri have a thicker cell wall than Pyrolobus fumarij? D.

Since the discovery of extremophiles, micro-organisms that thrive in extreme environments, our understanding of where life can exist has changed. Some extremophiles live in hot, acidic sulfur springs and some even live near the openings of deep ocean hydrothermal vents.Based on our current knowledge of extremophiles that exist on planet Earth, what does the existence of life in such extreme environments say about the possibility of life on other planetsarrow_forward
