how does energy acquisition in the deep sea differ from energy acquisition near the oceans surface?\na. organisms in the deep sea acquire energy directly from the sun.\nb. organisms near the oceans surface rely on chemosynthesis rather than photosynthesis.\nc. organisms in the deep sea do not have direct access to sunlight.\nd. organisms in the deep sea have no means to obtain energy unless they travel to the oceans surface.

Answer

Brief Explanations:

  • Option a: Incorrect. Organisms near the surface rely on photosynthesis (using sunlight), while deep - sea organisms do not have direct access to sunlight and thus cannot acquire energy directly from the sun.
  • Option b: Correct. Organisms near the ocean's surface use photosynthesis (which requires sunlight), and deep - sea organisms (where there is no sunlight) rely on chemosynthesis (using chemical energy from sources like hydrothermal vents).
  • Option c: Incorrect. It is a wrong statement as it is the opposite of the correct energy acquisition mechanisms. Organisms near the surface have access to sunlight for photosynthesis, and deep - sea organisms lack direct sunlight access.
  • Option d: Incorrect. Deep - sea organisms have ways to obtain energy (such as chemosynthesis, consuming organic matter that sinks from the surface etc.), just not through direct sunlight - based photosynthesis.

Answer:

b. Organisms near the ocean's surface rely on photosynthesis rather than chemosynthesis.
