Multiple Choice
How does energy acquisition in the deep sea differ from energy acquisition near the ocean's surface?
A
Energy acquisition in the deep sea is mainly through aerobic respiration.
B
Deep-sea organisms primarily rely on chemosynthesis for energy acquisition.
C
Deep-sea organisms primarily rely on photosynthesis for energy acquisition.
D
Deep-sea organisms use fermentation as their primary energy source.
Verified step by step guidance
1
Identify the primary energy sources available in the deep sea environment, considering the absence of sunlight.
Understand the process of chemosynthesis, where organisms convert inorganic molecules (like hydrogen sulfide) into organic matter using chemical energy.
Compare chemosynthesis with photosynthesis, noting that photosynthesis requires sunlight, which is not available in the deep sea.
Consider the role of hydrothermal vents in providing the necessary chemicals for chemosynthesis in deep-sea ecosystems.
Evaluate why aerobic respiration and fermentation are less likely to be primary energy sources in the deep sea due to the specific environmental conditions.
