Moon jellyfish (*Aurelia aurita*) thrive in warmer ocean waters, which speed up their reproduction. However, warmer water also contains less dissolved oxygen, which jellyfish need to survive. While modest temperature increases cause jellyfish populations to grow, extreme temperature increases deplete oxygen to levels that limit jellyfish survival. Thus, in areas experiencing extreme ocean warming, moon jellyfish populations will likely

Which choice most logically completes the text?

  1. A
    adapt to survive without any dissolved oxygen in the ocean.
  2. B
    migrate to even warmer waters to find higher levels of dissolved oxygen.
  3. fail to sustain their growth despite the initial reproductive benefits of warmer water.Cevap
  4. D
    grow much faster than they would in waters with moderate temperature increases.

Cevap

The correct answer is that the moon jellyfish populations will fail to sustain their growth despite the initial reproductive benefits of warmer water.
The text states that modest temperature increases help moon jellyfish populations grow by speeding up reproduction, but extreme temperature increases deplete dissolved oxygen to levels that limit survival. Therefore, in areas with extreme warming, the lack of oxygen will prevent the population from growing as expected, constraining their numbers despite the warmth.

Adım Adım Çözüm

1
Identify the initial effect of warmer water on moon jellyfish.
Warmer waters speed up reproduction and cause populations to grow.
To establish the positive baseline effect of temperature.
2
Identify the limiting factor introduced by warmer water.
Warmer water contains less dissolved oxygen, and extreme increases lower oxygen to levels that limit survival.
To identify the constraint that counteracts the positive effect of temperature.
3
Synthesize the two effects under extreme warming conditions.
The limiting factor (lack of oxygen) will constrain growth, preventing the population from growing indefinitely despite the warm water.
To draw a logical conclusion based on all provided premises.
