Question

1. in a short paragraph, construct an argument supported by evidence as to whether or not the physical components of an ecosystem can affect the population of microorganisms that live in it.

sentence 1: yes, the physical components of an ecosystem can affect the population of microorganisms that live in it.
sentence 2: in the geothermal environment of yellowstones grand prismatic hot spring, ____ and ____ create places that only certain thermophiles can survive in.
sentence 3: for example, __________, a heat - loving bacterium, thrives in temperatures near __________ where most other life forms would die.
sentence 4: meanwhile, cooler areas closer to the edge away from the center support _________ that prefer more moderate temperatures.
sentence 5: in addition, the ph of the water — whether ____ or ____ — also determines which bacteria can maintain homeostasis.
sentence 6: for example, ______________, another thermophile, can survive at a ph of _______, but would ____ if the ph went any higher or lower.
write 2 more sentences (sentences 7 - 9) on your own to answer question 2 in your paragraph. paste all the sentences in a paragraph below.

Explanation:

• Sentence 2: High temperatures and mineral - rich waters are typical physical components in a geothermal environment that limit microbial survival.
• Sentence 3: Thermus aquaticus is a well - known heat - loving bacterium, and high temperatures (e.g., 70 - 80°C) are its preferred range.
• Sentence 4: Microorganisms other than extreme thermophiles can live in cooler areas.
• Sentence 5: pH can be acidic or alkaline, which is an important physical - chemical property.
• Sentence 6: Sulfolobus acidocaldarius is an example of a thermophile with a specific pH range (e.g., pH 2 - 3), and it would die outside that range.

Answer:

Sentence 1: Yes, the physical components of an ecosystem can affect the population of microorganisms that live in it.
Sentence 2: In the geothermal environment of Yellowstone’s Grand Prismatic Hot Spring, high temperatures and mineral - rich waters create places that only certain thermophiles can survive in.
Sentence 3: For example, Thermus aquaticus, a heat - loving bacterium, thrives in temperatures near 70 - 80°C where most other life forms would die.
Sentence 4: Meanwhile, cooler areas closer to the edge away from the center support microorganisms that prefer more moderate temperatures.
Sentence 5: In addition, the pH of the water—whether acidic or alkaline—also determines which bacteria can maintain homeostasis.
Sentence 6: For example, Sulfolobus acidocaldarius, another thermophile, can survive at a pH of 2 - 3, but would die if the pH went any higher or lower.
Sentence 7: The availability of water (e.g., in arid vs. humid ecosystems) also impacts microbial populations. In arid regions, only xerophilic (dry - loving) microorganisms can survive.
Sentence 8: Light availability (in aquatic ecosystems, for photosynthetic microorganisms) is a physical component. Photosynthetic bacteria like cyanobacteria need sufficient light for photosynthesis.
